Rheumatoid arthritis is an autoimmune disorder where the immune system attacks the body’s own tissues, particularly the joints. It can cause inflammation, pain, and swelling in the affected areas. It is a chronic condition, and there is no cure. Treatment focuses on managing the symptoms.
Osteoarthritis is a degenerative joint disorder. It is caused by the gradual breakdown of cartilage, the tissue that cushions the ends of bones in a joint. This can cause pain, swelling, and stiffness in the affected areas. It is most common in older adults, but can affect people of any age. Treatment focuses on managing pain and maintaining joint function.
