Foot problems caused by RA commonly occur in the forefoot (the ball of the foot, near the toes), although RA can also affect other areas of the foot and ankle. The most common signs and symptoms of RA-related foot problems, in addition to the abnormal appearance of deformities, are pain, swelling, joint stiffness and difficulty walking.
Deformities and conditions associated with RA may include:
- Rheumatoid nodules (lumps), which cause pain when they rub against shoes or, if they appear on the bottom of the foot, pain when walking
- Dislocated toe joints
- Heel pain
- Achilles tendon pain
- Flatfoot ankle pain
