Arthritis can be an extremely debilitating affliction for those it affects. It is a fairly common condition, which is suffered by millions of people around the world. It affects the joints of the body and can cause problems in everyday life for sufferers due to a lack of mobility and pain it causes. This can make walking difficult if the hip, knee or ankle joint is affected and can result in a lack of dexterity when the finger and wrist joints are arthritic.
