Answer
Arthritis
Arthritis is a condition characterized by inflammation of the joints, which can lead to pain, swelling, stiffness, and reduced range of motion. It may result from injury, wear and tear, or autoimmune diseases that affect the joints. Treatment often involves pain management through medication, physical therapy, and lifestyle modifications such as exercise and a balanced diet. In severe cases, joint replacement surgery may be considered.
