Usually, if you have rheumatoid arthritis, you may experience joint pain, swelling, and stiffness in the same joints on both sides of your body. This symmetric distribution of affected joints is a classic feature of RA. In several cases, the small joints of both hands, wrists, and feet are commonly affected. There can also be joint pain and swelling in both knees, ankles, shoulders, elbows, and both sides of the hips in the early stages of RA.
However, while this symmetry is common, not everyone with the inflammatory disorder has this symmetric polyarticular form of arthritis. The way each symptom affects an individual may differ from person to person and may also change throughout the day or week. This means that though you may not have symptoms on both sides of your body at the early stages of the disease, joint pain and swelling may become symmetrical as your RA progresses.
