Hand rheumatoid arthritis is manifested by symmetrical painful swelling at the joints of wrists, large knuckles (metacarpophalangeal joints), and middle knuckles (proximal interphalangeal joints) accompanied by morning stiffness. The patient experiences difficulty in making a fist and performing small activities like using a smartphone, writing, typing, or preparing meals. If not treated, it can develop into rigid, rounded painful rheumatoid nodules at the affected areas, including fingers, wrists, forearms, and elbows, followed by joint deformities.
