Reactive arthritis most typically results in inflammation of the urogenital tract, the joints, and the eyes. Less common symptoms are mouth ulcers and skin rashes. Any of these symptoms may be so mild that patients do not notice them. They usually come and go over a period of several weeks to several months.
Urogenital Tract Symptoms
Reactive arthritis often affects the urogenital tract, including the prostate or urethra in men and the urethra, uterus, or vagina in women. Men may notice an increased need to urinate, a burning sensation when urinating, and a fluid discharge from the penis. Some men with reactive arthritis develop prostatitis (inflammation of the prostate gland). Symptoms of prostatitis can include fever and chills, as well as an increased need to urinate and a burning sensation when urinating.
Women with reactive arthritis may develop problems in the urogenital tract, such as cervicitis (inflammation of the cervix) or urethritis (inflammation of the urethra), which can cause a burning sensation during urination. In addition, some women also develop salpingitis (inflammation of the fallopian tubes) or vulvovaginitis (inflammation of the vulva and vagina). These conditions may or may not cause any arthritic symptoms.
Joint Symptoms
The arthritis associated with reactive arthritis typically involves pain and swelling in the knees, ankles, and feet. Wrists, fingers, and other joints are affected less often. People with reactive arthritis commonly develop inflammation of the tendons (tendinitis) or at places where tendons attach to the bone (ethesitis). In many people with reactive arthritis, this results in heel pain or irritation of the Achilles tendon at the back of the ankle. Some people with reactive arthritis also develop heel spurs, which are bony growths in the heel that may cause chronic (long-lasting) foot pain. Approximately half of people with reactive arthritis report low-back and buttock pain.
Reactive arthritis also can cause spondylitis (inflammation of the vertebrae in the spinal column) or sacroiliitis (inflammation of the joints in the lower back that connect the spine to the pelvis). People with reactive arthritis who have the HLA-B27 gene are even more likely to develop spondylitis and/or sacroiliitis.
Eye Involvement
Conjunctivitis, an inflammation of the mucous membrane that covers the eyeball and eyelid, develops in approximately half of people with reactive arthritis. Some people may develop uveitis, which is an inflammation of the inner eye. Conjunctivitis and uveitis can cause redness of the eyes, eye pain and irritation, and blurred vision. Eye involvement typically occurs early in the course of reactive arthritis, and symptoms may come and go.
Other Symptoms
Between 20 and 40 percent of men with reactive arthritis develop small, shallow, painless sores (ulcers) on the end of the penis. A small percentage of men and women develop rashes or small, hard nodules on the soles of the feet and, less often, on the palms of their hands or elsewhere. In addition, some people with reactive arthritis develop mouth ulcers that come and go. In some cases, these ulcers are painless and go unnoticed.
Who Gets Reactive Arthritis?
Evidence shows that although men are nine times more likely than women to develop reactive arthritis due to venereally acquired infections, women and men are equally likely to develop reactive arthritis as a result of food-borne infections. Women with reactive arthritis often have milder symptoms than men.
Is Reactive Arthritis Contagious?
Reactive arthritis is not contagious; that is, a person with the disorder cannot pass the arthritis on to someone else. However, the bacteria that can trigger reactive arthritis can be passed from person to person.
