Can joint pains affect the physically fit?

Joint pains can affect even a physically fit person. Contrary to the common perception, joint pain is no longer associated with old age; it could affect a person of any age group even the younger people. Most doctors recommend the use of pads round the knees in cases of knee joint pain to provide a cushion and ensure that there is no further damage. Many a times, knee pain sufferers also get a feeling of grinding. This feeling is caused when there is a complete tear of the cartilage and the bones start brushing against each other. Injuries to the tendon can cause knee pain.
