What is Reactive Arthritis?
Reactive arthritis is a form of arthritis, or joint inflammation, that occurs as a “reaction” to an infection elsewhere in the body. Reactive arthritis is also known as Reiter’s syndrome, and your doctor may refer to it by yet another term, as a seronegative spondyloarthropathy. The seronegative spondyloarthropathies are a group of disorders that can cause inflammation throughout the body, especially in the spine. 12.
