I have a bad knot up and around my right shoulder blade for 2 yrs now. I cant do over head presses anymore only back movements i can do is chinups. I can incline and flat bench no probs. Read some stuff on ppl lacking calcium and magnesium having bad leg cramps and knots. Anyone else have anything likes this. i use ice and massage the area to give a temp relief. any supps i may need or equipment that can get rid of this knot? thanks
