Knee pain can have causes that aren't due to underlying disease. Examples include heavy physical activity, lack of use, injuries such as sprains or strains, sitting in a constrained area, or sitting on knees for a prolonged period.
Self-treatment
Losing weight may help relieve long-term knee pain. For new pain, resting, applying ice several times a day, keeping the injured area elevated, and wrapping the area with an elastic bandage may also help. Using your Myoballs to roll you upper and lower leg well definately help to breakup tighness and send more blood to area, which promote healing.
