Rheumatoid arthritis (RA)
Rheumatoid arthritis (RA) is a long-term autoimmune disorder that primarily affects joints. It typically results in warm, swollen, and painful joints. Pain and stiffness often worsen following rest. RA presents itself most in the wrists and hands but can also affect the feet.
Foot symptoms in RA can take many forms, including pain in the joints, stiff ligaments, or constant aching. Symptoms are generally worse after a lot of standing, walking, or running. The onset of foot pain is gradual for some people with RA and immediate for others. At some point, though, most people with this disease discover that their foot joint pain makes it very painful to walk. RA can affect the foot in a manner of ways consisting of heel pain, nerve impingements/compressions or certain bunions.
