Sores, blisters, or ulcers around the genitals can happen for many reasons including sexually transmitted infections (STIs), irritation, or skin conditions.
Quick answers about genital sores, possible causes, and when to seek help.
Genital sores may be caused by STIs such as herpes or syphilis, skin irritation, allergies, friction, or other skin conditions. The cause can vary depending on whether the sores are painful, itchy, or changing over time.
Yes. Genital sores can be a sign of an STI, especially if they are painful, come in clusters, keep returning, or are linked with discharge, burning when urinating, fever, or swollen glands.
Genital herpes can cause small blisters or painful sores that may break open and heal over time. Some people also get tingling, itching, or burning before the sores appear.
Syphilis can cause a sore or ulcer that may not be painful. It is important to get tested because syphilis may not always cause obvious symptoms at first.
Get tested if the sores are new, persistent, painful, recurring, or if you recently had unprotected sex or a partner has symptoms or a positive STI result.
Seek urgent care if you have fever, severe pain, rapidly spreading sores, trouble passing urine, or you feel very unwell.
Some sores may heal on their own, but the cause may still need treatment. It is best not to keep guessing or repeatedly self-treating without a diagnosis.
