2-13. RHEUMATOID ARTHRITIS
Rheumatoid arthritis (RA) is a disease that affects the synovium (lining of the joints). The small joints of the feet, the metatarsal joints, and the toes are often affected by RA. This disease can strike at any age. The exact cause is unknown, but emotional stress has been known to trigger the disease. Swelling, pain, and warmth in the affected joints are symptoms of RA. For best results, treatment should be started early; otherwise, the disease can be crippling and disabling to the patient.
