Causes of arthritis-
The major cause of the pain associated with arthritis is by damage of the joints. Joints are made up of the following parts:
o Cartilage: It is a hard, but slick, coating on the ends of bones. Cartilage allows bones of the joint to slide smoothly over each other.
o Joint capsule: Joint capsule is a tough membrane encloses all the joint parts.
o Synovium: Synovium is a thin membrane lines the joint capsule and secretes synovial fluid. It lubricates the joint and nourishes the cartilage.

Damage to the joints
The two main type of arthritis damage the joints in the following ways.
o Osteoarthritis- In osteoarthritis, wear-and-tear damage to cartilage can result in bone grinding directly on bone. This can cause pain and restricts the movement. This wear and tear can occur over many years, or it can be hastened by a joint injury or infection.
o Rheumatoid arthritis- In rheumatoid arthritis, the body's immune system attacks joints and inflames the synovium. This causes swelling, redness and pain. The disease can eventually destroy cartilage and bone within the joint over the time.
