What I do for the pain to go away is: put ur hand into a sort of C shape, place ur hand on ur arm, in the middle starting next to ur elbow, then use ur thumb and top fingers to squeeze (but not too hard) all the way down to the tip of the middle finger. This process will relieve stress and soreness. If u need a medicated cream to make it slippery, that may also help while massaging.
