I am an Athletic Trainer and when we have cases of tennis elbow we do a technique called grastons. It will provide some immediate relief but I am not going to lie……it is PAINFUL while being done. You will bruise it will hurt for a few days but with this and some rehab and treatments as far as ultrasounds it will get better. You can see if your doc will write you a script for some P.T. for some iontophoresis(injection of a steroid through electrical stimulation directly to the affected area) may also help but it can get spendy with all of those PT visits. There is also a technique called A.R.T. this is also quite painful but another option if no one around is graston certified. If you would like more information PM me and I can try and help you out with a at home program you can try first.
