And/or tell you that you have one leg longer than the other. Or is that chiropractors?
To the OP: As others have said, rest is very important. My lateral epicondylitis was pretty much cured after six months and two steroid injections, then I set it off all over again by being a bit careless while doing some DIY.
It's now pretty much gone - although do I still get the odd twinge - but it had taken over a year to get to a point where I felt confident about crimping hard with that arm again. During that time I had a total of three steroid injections and lots of visits to the physio involving remedial massage and exercises. I did get ultrasound treatment early on but that didn't seem to help at all. The last half dozen or so physio visits included acupuncture along with the massage. That did seem to help a lot in my case, but I wouldn't go so far as to recommend it to others simply on that basis.
My physio did quite a lot of work on my posture, along with massage and other treatments around my shoulder and neck. Their justification for this was that they suspected that my tennis elbow could be being caused or exacerbated by tightness in muscles in that area, and related problems with the radial nerve. Maybe it's something similar that's causing your two physios to tell you apparently conflicting things? I'd certainly suggest that you mention to each of them what the other has told you, and see if they can come to some kind of agreement as to the best overall package of treatment for you.
Good luck with it, I know from experience how frustrating such an apparently trivial but persistent injury can be.
