Symptoms
By Mayo Clinic staffSexually transmitted infections (STIs) have a range of signs and symptoms. That's why they may go unnoticed until complications occur or a partner is diagnosed. Signs and symptoms that might indicate an STI include:
- Sores or bumps on the genitals or in the oral or rectal area
- Painful or burning urination
- Discharge from the penis
- Vaginal discharge
- Unusual vaginal bleeding
- Sore, swollen lymph nodes, particularly in the groin but sometimes more widespread
- Lower abdominal pain
- Rash over the trunk, hands or feet
Signs and symptoms may appear a few days to years after exposure, depending on the organism. They may resolve in a few weeks, even without treatment, but progression with later complications — or recurrence — sometimes occurs.
When to see a doctor
See a doctor immediately if:
- You are sexually active and you believe you've been exposed to an STI
- You have signs and symptoms of an STI
Make an appointment with a doctor for STI counseling and, if appropriate, screening tests:
- When you consider becoming sexually active, or when you're 21 — whichever comes first
- Before you start having sex with a new partner
