Sudden pain accompanied by swelling and redness in one or more of the joints could indicate reactive arthritis. This inflammatory condition most often affects the knees, toes, hips, and ankles. In most cases, an infection causes the symptoms. The good news is that there are effective treatments for reactive arthritis, and when addressed properly, many people do not experience long-term side effects.
The most noticeable symptom of reactive arthritis is pain that appears in the affected joints. Pain usually appears suddenly, but it can also appear gradually. Most often, discomfort develops in the joints of the knees, feet, toes, hips as well as the ankles. Pain can make it difficult to walk and may cause other complications. Some people will also experience pain that affects the genital tract, thus causing pain during urination. In some cases, discharge may be present. Contact your doctor if you notice pain that lasts for a long time.
