Rheumatoid arthritis may cause pain, swelling, stiffness, and tenderness
in foot joints. If the disease progresses, joints may become distorted and
disabled. Pain and tenderness is common under the ball of the foot. The joints
between the foot and the toes (metatarsophalangeal joints) swell and move,
causing the toes to curl and overlap. The big toe may bend inward (hallux
valgus). The middle toes may bend into a claw-shaped curl (hammer toe).
