Arthritis is a term used to describe over 100 medical conditions that cause pain and inflammation in the joints. The most common forms are osteoarthritis and rheumatoid arthritis. Osteoarthritis generally affects elderly patients and causes cartilage in the joints to wear down over time, while rheumatoid arthritis is an autoimmune disorder that causes swelling and damage to joint lining. Some other types of arthritis include infectious arthritis caused by bacteria/viruses, and juvenile rheumatoid arthritis which affects children. Symptoms vary depending on the type but can include joint pain, stiffness, swelling and reduced mobility. Treatment involves medications like NSAIDs to reduce inflammation, physical/occupational therapy, weight loss if overweight, and home remedies such as supplements and herbal remedies
