My knee Cap was burning, at night got numb... it went away but accasionally, i have numbness and tingling radiating into lower legs... i would describe it more as discomfort... seems like neurological... knees get
redish after activity, like under my skin... I know that any exersise with flexing cause pain on the next day... now i even seat with my legs straight... I got foam roller... i want to ask your opinion about using it?
