One month ago, i get a bruise above my knee in the thigh muscle lower part, at first swelling, i put ICE in the first two days, then i see the blood in blow under skin in the injury area, i thought it needs to be warmed up in the next days i used hot Compresses for many days, i went to doctor many times he used ultra sound and electric current to activate the muscle but i still feel all the time when i stand up that the end of the muscle ( i think it is rectus femoris tendon ) has tension.
