My father has been having pretty heavy aches and pains in his knees for a while now. He said the joints in his knees hurt so bad last night that it interupted his sleep and had to take some aspirin to heal the pain. I'm assuming that his work contributes a lot to this, as he stands on his feet all day, runs here and there, and neals down a lot during his 12-14 hour days. Does anyone have any ideas as ways to help his problem? Any helpful input is great, thanks!
