Arthritis is inflammation of the joint. The main symptoms are pain and/or stiffness. Usually arthritis is a condition experienced as one grows old. Most common is 50+. Arthritis is general can be classified as 2, degenerative and infective. Both are conditions which are not very easy to handle. Degeneration is the law of nature. But it can be definitely slowed down if it is happening due to lifestyle issues. One major factor leading to degenerative arthritis is sedentary life and constant trauma on the joints due to excess weight. Weight bearing joints like knees, hip and ankles get affected faster due to obesity and they degenerate faster. Injury and improper handling of the joint can also lead to arthritis.
