You should consult a venereologist when you notice genital discharge, burning during urination, persistent itching, sores, blisters, warts, unexplained rashes, pelvic pain, testicular discomfort, pain during sex, unusual bleeding or symptoms after a possible sexual exposure. You should also seek advice when a partner has been diagnosed with a sexually transmitted infection, even if you feel completely well.
A venereologist is a doctor trained to assess sexually transmitted infections, commonly called STIs or STDs, and related genital skin conditions. Many infections cause mild or no symptoms, while conditions that are not sexually transmitted can look similar. This guide explains 12 warning signs, when care is urgent, what happens during a consultation and how to seek appropriate STD treatment in Kathmandu without relying on guesswork or self-medication.
Medical note: This article provides general education and cannot diagnose an individual condition. Seek professional assessment for symptoms, possible exposure, pregnancy-related concerns or urgent warning signs.
What does a venereologist treat?
A venereologist evaluates, diagnoses and manages sexually transmitted infections and related conditions affecting the genital area, anus, mouth or surrounding skin. Depending on the history and examination, this may include chlamydia, gonorrhoea, syphilis, genital herpes, HPV-related warts, trichomoniasis, HIV-related exposure concerns, hepatitis B exposure, pubic lice, scabies and molluscum contagiosum.
The consultation is not simply about confirming an STD. Genital itching, bumps, redness or discharge can also result from fungal infection, eczema, contact irritation, balanitis, folliculitis, urinary infection or another non-STI condition. A specialist considers both infectious and non-infectious possibilities before recommending tests or treatment.
In many healthcare systems, venereology is combined with dermatology because several infections produce visible changes in the skin or mucosal surfaces. Dr. Parash Shrestha is independently listed by B&B Hospital as a Consultant Dermatologist and Venereologist with MBBS, MD and FAM qualifications and Nepal Medical Council registration number 7527.

Why should STI symptoms be assessed rather than guessed?
The same symptom can have several causes. Burning during urination may occur with urethritis, a urinary infection or irritation. A genital bump could be a wart, ingrown hair, skin tag, cyst, molluscum lesion or normal anatomical variation. A rash may be related to an STI, allergy, fungal infection, medicine or an unrelated skin disease.
Symptoms alone cannot identify the organism or determine the correct treatment. WHO notes that many STIs are asymptomatic and that untreated infections may contribute to infertility, pregnancy complications, cancers and increased HIV risk. WHO also identifies antimicrobial-resistant gonorrhoea as a major challenge, making unverified antibiotic use especially concerning.
The practical rule is simple:
A symptom is a reason for assessment, not a diagnosis.
When should you consult a venereologist? 12 warning symptoms
1. Unusual vaginal, penile or anal discharge
A new discharge that is different in colour, amount, smell or consistency deserves clinical evaluation, particularly when it follows a new or potentially concerning sexual exposure. Discharge may occur with gonorrhoea, chlamydia, trichomoniasis, urethritis, cervicitis or another infection. It can also result from conditions that are not sexually transmitted.
WHO lists abnormal vaginal or urethral discharge among common STI symptoms. Gonorrhoea may cause white, yellow or greenish penile discharge, while vaginal infection may produce increased discharge with or without other symptoms. Chlamydia is frequently symptomless but can also cause changes in vaginal or urethral discharge.
Do not select an antibiotic based only on the appearance of the discharge. The doctor may need to consider the site of exposure, symptom timing, examination findings and results from a urine or swab test.
Arrange a consultation promptly when: the discharge is persistent, recurrent or accompanied by pain, bleeding, fever or a partner’s STI diagnosis.
2. Burning or pain while urinating
Painful urination, also called dysuria, is a common reason to consult an STD doctor in Nepal. It may occur with gonorrhoea, chlamydia, trichomoniasis or inflammation of the urethra. Urinary infection, stones, dehydration, local irritation and other conditions may produce similar discomfort.
CDC guidance describes dysuria, urethral itching and discharge as possible features of urethritis. Urethritis may be caused by infectious or non-infectious conditions, which is why clinical assessment and appropriate testing matter.
Seek assessment when the burning follows possible exposure, occurs with discharge, keeps returning or does not improve. Inability to pass urine, severe pain or rapidly increasing swelling requires urgent medical care rather than a routine appointment.
3. Persistent genital itching, redness or irritation
Genital itching is not automatically an STI. Common alternatives include fungal infection, eczema, contact dermatitis, shaving irritation, balanitis, sensitivity to soaps or products and other inflammatory skin conditions.
Itching may, however, accompany trichomoniasis, herpes, pubic lice, scabies or genital warts. Trichomoniasis can produce itching and urinary discomfort, while herpes symptoms may begin with tingling, itching or burning near the affected area.
A venereologist who also has dermatology training can examine the distribution and appearance of the skin changes. Persistent scratching may worsen irritation, damage the skin barrier and obscure the condition’s original appearance.
Consult a specialist when itching lasts, recurs, spreads, appears after possible exposure or occurs with discharge, sores, bumps or swelling. Avoid repeatedly applying steroid, antifungal or combination creams without a diagnosis.
4. Sores, ulcers or blisters around the genitals, anus or mouth
Any new genital sore, ulcer or blister should be assessed. Genital herpes may produce painful blisters or ulcers, while primary syphilis can cause a painless sore that may heal even though the infection remains. Other possible causes include trauma, inflammatory disease, medicine reactions and non-sexually transmitted infections.
WHO explains that many people with syphilis do not notice symptoms. When a primary sore develops, it may be painless and disappear without treatment. Herpes can cause painful, recurring blisters or ulcers, although some infections are mild or unrecognized.
Do not wait for a sore to disappear before requesting advice. Healing does not prove that an infection has cleared. Early assessment may also improve the chance of obtaining a useful sample.
5. New warts, lumps or bumps in the private area
A new bump can understandably cause concern, but not every bump is an STI. HPV-related genital warts may appear as small rough growths around the penis, vagina or anus. Similar-looking changes include skin tags, ingrown hairs, folliculitis, cysts, molluscum contagiosum and normal anatomical structures.
WHO states that most HPV infections cause no symptoms, while some produce genital warts that may itch, bleed or cause discomfort. A clinician should examine uncertain lesions before treatment because the correct approach depends on the diagnosis, location, number, size and individual factors.
Do not cut, burn or squeeze a genital lesion. Ordinary hand-and-foot wart removers may be unsuitable for sensitive genital skin.
6. Pelvic or lower-abdominal pain
Lower-abdominal or pelvic pain has many possible gynaecological, urinary, gastrointestinal and musculoskeletal causes. In a sexual-health context, it may be associated with pelvic inflammatory disease or complications of infections such as chlamydia and gonorrhoea.
WHO identifies gonorrhoea and chlamydia as major causes of pelvic inflammatory disease and infertility in women. Pain may be mild at first, so it should not be dismissed when it occurs with abnormal discharge, bleeding, pain during sex, fever or possible STI exposure.
Arrange timely assessment for persistent or recurrent pelvic pain.
Seek urgent care when pelvic pain is severe or occurs with fever, vomiting, fainting, pregnancy or significant illness.
7. Testicular pain, tenderness or swelling
Testicular pain or swelling requires careful assessment because possible causes range from infection and inflammation to conditions that need emergency treatment.
STI-related epididymitis may produce one-sided testicular pain, tenderness or swelling. Sudden severe pain may also be caused by testicular torsion, which requires emergency assessment. CDC guidance describes pain, tenderness and swelling as common clinical features of acute epididymitis.
A routine venereology consultation may be appropriate for mild discomfort associated with discharge or urinary symptoms. Sudden, severe or rapidly worsening testicular pain should be evaluated immediately.
Do not attempt to identify the cause from pain intensity alone. Examination, urine testing, STI testing or imaging may be needed.
8. Pain during sexual activity
Pain during sex may be related to infection, inflammation, dryness, pelvic-floor problems, skin disease, trauma or other gynaecological or urological conditions.
Trichomoniasis can be associated with pain during intercourse, while pelvic inflammatory disease may produce deeper pelvic discomfort.
Pain that is new, persistent or linked with discharge, bleeding, sores or pelvic pain should be evaluated. A venereologist can assess STI-related causes and refer to gynaecology, urology or another specialist when a different condition is more likely.
The objective is not to assume that the pain is caused by an infection. It is to identify the cause and establish the appropriate care pathway.
9. Bleeding between periods or after sexual activity
Unexpected bleeding between menstrual periods or after sex should not be ignored. Chlamydia and gonorrhoea may cause bleeding between periods, while cervical inflammation and several non-STI conditions can produce similar symptoms.
Persistent bleeding also requires assessment for cervical and other gynaecological causes. HPV-related cervical cell changes often produce no early symptoms, which is why age-appropriate cervical screening remains important. When symptoms do occur, bleeding after sex or between periods requires medical evaluation.
Seek medical review rather than assuming the bleeding is caused by an STI. The appropriate professional may be a venereologist, gynaecologist or both.
10. Anal pain, discharge, bleeding or painful bowel movements
Rectal STIs may produce anal pain, discharge, bleeding, itching or discomfort during bowel movements. Gonorrhoea and chlamydia can affect the rectum, and some rectal infections cause few or no symptoms.
These symptoms may also result from haemorrhoids, fissures, inflammatory bowel disease, skin irritation or another condition. An accurate exposure history matters because the correct test depends partly on the anatomical site involved. A urine test alone may not answer every question.
Arrange assessment when symptoms persist, follow possible exposure or occur with fever, sores or a new rash. Heavy bleeding, severe pain or significant illness requires urgent medical care.
11. A new rash, especially after possible exposure
A widespread or unusual rash can have many causes, including viral illness, allergy, medicine reactions and dermatological disease.
Syphilis is an important venereological consideration because secondary syphilis may produce a non-itchy rash, including on the palms and soles. The rash and other symptoms may disappear without treatment even though the infection remains.
A clinician may ask about earlier sores, swollen lymph nodes, fever, medicines and exposure history before selecting tests.
Seek prompt assessment when a rash follows possible exposure, particularly when accompanied by a sore, fever or swollen glands. A widespread rash with severe illness, eye problems or neurological symptoms requires urgent evaluation.
12. Symptoms that improve and return
Symptoms that repeatedly disappear and return deserve medical review. Herpes can recur, while untreated or partially treated infections may continue despite temporary improvement. Recurrent itching, discharge or irritation can also reflect a non-STI skin disorder, repeated exposure, reinfection or use of the wrong medicine.
WHO notes that herpes may produce recurring episodes, although later episodes are often shorter and less severe than the initial one.
Bring previous prescriptions and test reports to your appointment. Tell the doctor about antibiotics, creams or home remedies already used because they may affect symptoms, lesion appearance or test interpretation.
Recurring symptoms are particularly important when treatment was not completed, a partner was not evaluated or sexual contact resumed before the medically recommended time.
Symptom-to-action guide
| Symptom or situation | Possible categories—not a diagnosis | Recommended action |
|---|---|---|
| Discharge or burning urination | Urethritis, cervicitis, urinary or genital infection | Arrange timely examination and appropriate testing |
| Itching, redness or rash | STI, fungal infection, dermatitis or irritation | Consult rather than repeatedly self-treating |
| Sore, ulcer or blister | Herpes, syphilis or non-STI skin condition | Seek prompt assessment, ideally while visible |
| Wart, lump or bump | HPV wart, skin tag, cyst, folliculitis or normal variation | Have the lesion examined before treating it |
| Pelvic pain with discharge or bleeding | Reproductive-tract infection or another pelvic condition | Seek timely care; urgent if severe or accompanied by fever |
| Testicular pain or swelling | Infection, inflammation or an emergency condition | Seek immediate care when pain is sudden or severe |
| Possible HIV exposure within 72 hours | Time-sensitive prevention decision | Seek urgent PEP assessment |
| Exposure without symptoms | Asymptomatic infection remains possible | Discuss appropriate testing and timing |
This table is a decision aid, not a diagnostic tool. The most important distinction is between symptoms suitable for a prompt consultation and warning signs that require urgent or emergency care.
When should you consult a venereologist without symptoms?
You should consider consulting a venereologist even when you feel well if:
- A partner has been diagnosed with an STI
- You had a possible exposure
- A condom broke
- You are uncertain about when to test
- You are pregnant or planning pregnancy and have a relevant concern
- A healthcare professional has recommended screening
Many STIs cause no noticeable symptoms or symptoms so mild that they are not recognized. WHO’s 2025 STI fact sheet states that the majority of the more than one million curable STIs acquired globally each day are asymptomatic.
A negative result obtained too early may not exclude every infection. The appropriate test and timing depend on the infection being considered, the date and type of exposure, the body site involved and any medicine already taken.
A specialist helps answer three separate questions:
- Is testing indicated?
- Which test and sample site are appropriate?
- When will the result be meaningful, and is repeat testing required?
For broader information about infections and transmission, refer to the website’s guide to sexually transmitted diseases in Nepal.
Nepal’s National Centre for AIDS and STD Control also maintains national STI-management guidance and information on HIV testing and counselling services.
Which symptoms require urgent or emergency care?
Do not wait for a routine appointment when you have:
- A possible HIV exposure during the previous 72 hours
- Sudden or severe testicular pain
- Severe pelvic or lower-abdominal pain with fever, vomiting, fainting or significant illness
- Pregnancy with substantial symptoms or possible exposure
- Inability to pass urine
- Rapidly increasing genital swelling
- A widespread rash with severe illness, eye symptoms or neurological symptoms
- Sexual assault requiring urgent medical care and support
CDC guidance states that HIV post-exposure prophylaxis, known as PEP, must be started within 72 hours after a possible exposure. Earlier assessment is better because PEP is an emergency prevention measure.
Sudden testicular pain also needs emergency assessment because not every case is infection-related. Severe pelvic pain may require evaluation for STI complications and other urgent abdominal or gynaecological conditions.
What happens during a venereology consultation?
1. A private clinical discussion
The doctor generally asks about:
- Current symptoms
- When the symptoms began
- Recent possible exposure
- Previous STI history
- Medicine or antibiotic use
- Allergies
- Relevant pregnancy information
- Previous test results
- Symptoms or diagnoses in a partner
Accurate information helps the doctor select suitable tests. You do not need to diagnose yourself before the visit. Dates, symptoms, previous medicines and the body sites potentially exposed are more useful than trying to name the infection yourself.
Patients should ask the clinic how appointment information, records, test results and electronic communication are handled. The website should not make specific confidentiality promises until the clinic’s process and relevant exceptions have been confirmed.
2. A clinically relevant examination
An examination may be recommended when there is a visible rash, sore, wart, swelling or discharge.
The clinician should explain:
- Why the examination is being recommended
- Which area needs to be examined
- What information it may provide
- Whether a chaperone is available
- Whether the patient can pause or decline the examination
A photograph may help document a symptom that has changed, but it is not always a substitute for an in-person examination.
3. Tests selected for the individual situation
Testing may involve:
- A urine sample
- A blood sample
- A genital, oral or anal swab
- Microscopy
- Culture
- Serology
- PCR or another nucleic-acid test
Not every patient needs every test. WHO’s guidelines support evidence-informed assessment and management of symptomatic STIs, with testing and treatment selected according to the clinical situation and available resources.
A broad “all STI” package may still be incomplete when the wrong anatomical site is tested or testing is performed outside an appropriate time window. Clinical interpretation is as important as ordering the test.
4. Treatment, partner care or referral
Treatment depends on the confirmed or suspected condition, allergies, pregnancy status, previous medication and applicable clinical guidance.
Some bacterial and parasitic infections can be cured with appropriate medicines. Viral infections may require symptom control, recurrence management, monitoring or preventive advice rather than a promise of permanent cure.
Current or recent partners may also need testing, treatment or counselling. Partner care can reduce reinfection and further transmission.
Referral may be needed for:
- Gynaecological assessment
- Urological assessment
- HIV or infectious-disease care
- Pregnancy-related care
- Cervical screening
- Biopsy or surgical assessment
- Emergency care
- Sexual-assault care and support
Why can self-medication delay the correct diagnosis?
Using leftover antibiotics, sharing another person’s medicine or repeatedly applying mixed creams can create several problems.
The medicine may:
- Fail to treat the actual cause
- Cause side effects
- Temporarily suppress symptoms
- Alter the appearance of a lesion
- Affect later clinical interpretation
- Contribute to antimicrobial resistance
WHO identifies drug-resistant gonorrhoea as a major global public-health challenge. Responsible treatment therefore requires selecting medicines according to the likely or confirmed cause and applicable guidance not choosing an antibiotic simply because discharge or burning is present.
Before your appointment, record every medicine already taken. Bring the packaging or previous prescription when available.
How should you choose an STD doctor or venereologist in Kathmandu?
Look for verifiable specialist qualifications, professional registration and a scope of practice that includes both STI assessment and genital dermatology.
The clinician should:
- Explain the possible causes
- Recommend only clinically relevant tests
- Discuss limitations and uncertainties
- Explain whether repeat testing is needed
- Avoid unnecessary antibiotics
- Refer when another specialty is more appropriate
Useful questions to ask include:
- Which conditions could be causing my symptoms?
- Which tests are recommended, and why?
- Is this the correct time to test?
- Could medicine I already used affect the result?
- Does my partner need an assessment?
- Will follow-up or repeat testing be needed?
- Which symptoms require urgent care?
- How will my records and test results be handled?

- Appropriate testing depends on timing, exposure and the body site involved.
- Avoid using antibiotics or genital treatments without a clear diagnosis.
Frequently asked questions
What does a venereologist do?
A venereologist assesses and treats sexually transmitted infections and related genital conditions. The doctor may take a clinical history, examine visible skin or genital changes, recommend urine, blood or swab tests, prescribe appropriate treatment, discuss partner evaluation and refer to another specialist when necessary. A venereologist may also evaluate non-STI conditions that resemble sexually transmitted infections.
What is the difference between dermatology and venereology?
Dermatology focuses on conditions affecting the skin, hair and nails. Venereology focuses primarily on sexually transmitted infections and genital health concerns. The specialties frequently overlap because STIs can produce rashes, sores, warts and other skin or mucosal changes. A doctor qualified in both fields can assess whether a genital symptom is infectious, inflammatory or dermatological.
Does a dermatologist look at bumps on your private area?
Yes. A dermatologist may examine bumps, rashes, sores or other skin changes in the genital area when this is clinically necessary. A dermatologist trained in venereology can also assess whether the change may be an STI. The doctor should explain why an examination is needed, obtain consent and discuss privacy and chaperone arrangements before proceeding.
When should you see a venereologist?
See a venereologist when you have genital discharge, painful urination, persistent itching, sores, blisters, warts, pelvic pain, testicular discomfort, pain during sex, unusual bleeding or anal symptoms. Consultation is also appropriate after possible exposure, when a partner has been diagnosed with an STI or when screening is recommended despite having no symptoms.
Can an STI be present without symptoms?
Yes. Many STIs cause no symptoms or symptoms so mild that they are not recognized. A person may therefore have and transmit an infection without knowing. Testing decisions should be based on exposure history, individual risk, body sites involved and professional screening guidance—not only on whether visible symptoms are present.
Should I take antibiotics before visiting an STD doctor?
Do not start, share or reuse antibiotics unless a qualified clinician has prescribed them for your situation. The wrong antibiotic may not treat the actual condition, may cause side effects and may affect later assessment. Tell the doctor about every medicine already taken and bring previous prescriptions or test reports to the consultation.
