Start with the right question
A new sore on the penis, vulva or genital skin needs proper assessment. Pain, appearance and the number of ulcers can provide clues—but cannot confirm the diagnosis.
What conditions can cause genital sores?
Important infectious causes include primary syphilis and genital herpes. Other infections can cause ulcers less commonly, while non-infectious causes include friction, fixed drug eruption, inflammatory disease and trauma. Clinical context matters greatly.
Syphilis often causes a classically painless chancre; however, lesions can be atypical or painful. Herpes is often painful with grouped blisters or ulcers, but the presentation can vary. You cannot diagnose or exclude either infection using pain alone.
Why an ulcer that disappears may still matter
A syphilis chancre can heal even without antibiotic treatment. The visible sore disappearing does not mean the underlying infection has been cured. Evaluation is appropriate even if a lesion is already fading.
How clinicians choose tests
Assessment may include syphilis blood testing (both nontreponemal and treponemal tests) and, for an active lesion, HSV PCR or another locally available lesion test. If a lesion is very recent, initial syphilis serology can sometimes be negative, and repeat testing may be advised when suspicion remains high. Other ulcer tests and occasional biopsy depend on the clinical picture.
What should I avoid before examination?
Do not repeatedly apply corrosive liquids, combination steroid-antifungal creams or over-the-counter antibiotics to an undiagnosed sore. Try to avoid sexual contact until a clinician assesses the lesion and advises you. Do not delay assessment because the sore is small or painless.
When is same-day assessment important?
Rapidly expanding ulcers, severe pain, fever, marked swelling, inability to urinate, pregnancy with a new genital lesion, or significant immunosuppression merit urgent evaluation. Patients with eye, neurological or hearing symptoms alongside possible syphilis require prompt specialist assessment.
Frequently Asked Questions
Does every painless penile ulcer mean syphilis?
No. Syphilis is an important possibility, but appearance alone does not establish the cause.
Can an untreated syphilis sore heal?
Yes. The sore may resolve while infection persists, so assessment and appropriate treatment remain important.
Can early syphilis blood tests be negative?
Yes, particularly very early. A clinician may recommend follow-up testing based on timing and findings.
Should I send an intimate photograph on WhatsApp?
A detailed private photo is not required to request an appointment. Prefer examination in a suitable clinical setting.
