Rheumatic arthritis is an inflammatory connective tissue disease caused by infection with Group A beta-hemolytic streptococcus. It is primarily characterized by migratory pain in the major joints of the limbs and may also present with fever, rash, erythema annulare, subcutaneous nodules, chorea, and carditis. Osteoarthritis mainly affects the major joints such as the hands, knees, shoulders, and lumbar spine, often without migratory symptoms. This condition is a degenerative change, primarily seen in middle-aged and elderly individuals. The treatment of this disease mainly includes calcium supplementation, keeping the joints warm, taking non-steroidal anti-inflammatory drugs, and medications that improve the condition, mainly glucosamine sulfate and diacerein.
