Arthritis
Arthritis causes a reduction in cartilage (which increased the friction) between the joints. When cartilage becomes damaged or worn down, the affected joint usually becomes inflamed and restricts motion, causing pain. Osteoarthritis gradually develops as we age, whereas Rheumatoid Arthritis often has system-wide symptoms and a genetic relationship.

Blood flow and sensation are no longer properly regulated and may cause various problems in the muscles, bones, nerves, and skin.
