Sometimes it can be very hard to figure out where your knee pain is actually coming from from. Is it from the actual knee or is it from somewhere else? I was able to locate the source of my pain in my thigh, which was really tight and knotted, and I believe that knot was pulling on the inside of my knee. After I applied heat and vibration, the pain was gone! LTKActive LTKFindsUnder100 LTKOver40
