Reactive arthritis
Reiter syndrome; Post-infectious arthritis
Reactive arthritis is a group of conditions that may involve the joints, eyes, and urinary and genital systems. These areas become swollen and inflamed. It is often in response to infections.
Causes
The exact cause of reactive arthritis is unknown. It occurs most often in men younger than age 40. It may follow an infection in the urethra after unprotected sex. It can also follow an intestinal infection (such as food poisoning). However, the joint itself is not infected.
Certain genes may make you more likely to get this condition.
The disorder is rare in young children, but it may occur in teenagers.
Symptoms
Urinary symptoms will appear within days or weeks of an infection. These symptoms may include:
- Burning when urinating
- Fluid leaking from the urethra (discharge)
- Problems starting or continuing a urine stream
- Needing to urinate more often than normal
A low fever along with eye discharge, burning, or redness ( conjunctivitis or "pink eye") can develop over the next several weeks.

Exams and Tests
Your health care provider will diagnose the condition based on your symptoms. A physical exam may show signs of conjunctivitis or skin sores. All symptoms may not appear at the same time, so there may be a delay in getting a diagnosis.
You may have the following tests:

Treatment
The goal of treatment is to relieve symptoms and treat the infection that is causing this condition.
Eye problems and skin sores do not need to be treated most of the time. They will go away on their own.
Your provider will prescribe antibiotics if you have an infection. Nonsteroidal anti-inflammatory drugs (NSAIDs) and pain relievers may help with joint pain. If a joint is very swollen for a long period of time, you may have corticosteroid medicine injected into the joint.
Pain relievers
Over-the-counter (OTC) pain relievers can help relieve pain or lower a fever. Over-the-counter means you can buy these medicines without a prescript...
Physical therapy can help ease the pain. It can also help you move better and maintain muscle strength. Rarely, people with a severe case of the disease may need medicine to suppress the immune system.
Outlook (Prognosis)
Reactive arthritis may go away in a few weeks, but it can last for a few months. Symptoms may return over a period of years in up to half of the people who have this condition.
Rarely, the condition can lead to abnormal heart rhythm or problems with the aortic heart valve.
When to Contact a Medical Professional
See your provider if you develop symptoms of this condition.

Reactive arthritis is a disease which classically consists of inflammation of the joints (arthritis), urethra (urethritis), and eye. Reactive arthritis frequently includes skin manifestations and is thought to be triggered in some people by an infection. This is a fairly typical rash on the feet associated with Reiter syndrome. This type of rash may also appear on the hands.
