Common causes
Genital sores may be caused by herpes, syphilis, chancroid or non-infectious conditions.
- Herpes often causes clustered blisters or ulcers.
- Syphilis may cause painless chancres.
- Other causes include trauma, dermatitis and skin conditions.
Why prompt care matters
Some infections are highly treatable but can cause complications if ignored. Prompt assessment helps guide testing and treatment.
What to expect
A clinician may examine the lesion, ask about symptoms and order swab or blood tests.
