Arthritis is a general term used to describe a range of conditions affecting the joints, the areas where two or more bones meet. It is characterized by symptoms such as pain, stiffness, swelling, and reduced range of motion in the affected joints. There are many types of arthritis, with osteoarthritis and rheumatoid arthritis being among the most common. While arthritis is more commonly seen in older adults, it can affect people of all ages, including children. Treatment for arthritis often involves medication, physical therapy, lifestyle changes, and in severe cases, surgical intervention, all aimed at managing symptoms and improving quality of life.
