Osteoarthritis
Osteoarthritis is the most common form of arthritis. It is frequently called a degenerative joint disease or “wear and tear” arthritis. Although it can be brought on suddenly by an injury, its onset is generally gradual; aging brings on a breakdown in cartilage, and pain gets progressively more severe, although it can be relieved with rest. Dull, throbbing nighttime pain is characteristic, and it may be accompanied by muscle weakness or deterioration. Walking may become erratic. It is a particular problem for the feet when people are overweight, simply because there are so many joints in each foot. The additional weight contributes to the deterioration of cartilage and the development of bone spurs.
