I had tennis elbow at one time for almost 2 years, so bad i could hardly hold my tooth brush, had it shot up several times too, that only lasted for 2 weeks every time, the thing that got rid of it for me was theory where it was massaged with some kind of heat viberation deal ? They told me that calcium builds up around the pulled muscle and won't let it heal, the massage broke up the calcium and it was better in about 4 weeks and I have not had it again
