Know Arthritis

Arthritis is inflammation of one or more joints, which results in pain,  swelling, stiffness, and limited movement. Arthritis involves  the breakdown of cartilage. Cartilage normally protects the  joint, allowing for smooth movement. Cartilage also absorbs  shock when pressure is placed on the joint, like when you walk.  Without the usual amount of cartilage, the bones rub together,  causing pain, swelling (inflammation), and stiffness.
