Symptoms

The signs and symptoms of reactive arthritis generally start one to four weeks after exposure to a triggering infection. They might include:

• Pain and stiffness. The joint pain associated with reactive arthritis most commonly occurs in your knees, ankles and feet. You also might have pain in your heels, low back or buttocks.
• Eye inflammation. Many people who have reactive arthritis also develop eye inflammation (conjunctivitis).
• Urinary problems. Increased frequency and discomfort during urination may occur, as can inflammation of the prostate gland or cervix.
• Inflammation of soft tissue where it enters bone (enthesitis). This might include muscles, tendons and ligaments.
• Swollen toes or fingers. In some cases, your toes or fingers might become so swollen that they resemble sausages.
• Skin problems. Reactive arthritis can affect your skin a variety of ways, including a rash on your soles and palms and mouth sores.
• Low back pain. The pain tends to be worse at night or in the morning.

When to see a doctor

If you develop joint pain within a month of having diarrhea or a genital infection, contact your doctor.
