In a lot of cases not really necessary to see a doctor for tennis elbow. And info on this board will often be better than what a doctor will tell you.
Over the span of several decades, I've had GE once & TE on 3 occasions. Went to see the doc the 1st time I had TE (~35 yrs ago) even tho I was pretty sure what it was already. Wanted to see what he would prescribe & any wisdom he might provide. Got little bit of insight & a prescription for hi-potency IB, which health insurance paid for. So that was cool.
But I had actually gotten more info about causes & countermeasures from tennis coaches & my own research than what I had gotten from a medical doctor.
After that, never saw any need to seek the advice of a doc for either medial or lateral epicondylitis. Knew what I was dealing with & had a very good idea exactly what caused it. Would have gotten only very general advice from the doc. Don't believe he'd provide any details that I didn't already know.
The 3rd time I had gotten TE (~20 yrs ago), I was puzzled cuz I knew why I had gotten it 2x before and knew how to avoid it. But it occurred to me, after a couple of weeks, that the TE in my L elbow was a direct result of heel spurs on my R foot. Because I was not putting much weight on my R foot, in order to avoid significant pain, I would hit my one-handed Bh without loading & driving off my rear leg. As a result, I was putting undue stress on my L arm to hit my Bh shots. It is doubtful that most doctors would see that connection if they were not a tennis player with a one-handed Bh.
Nor would they have come up with unique solution that I had hit upon. I had noticed that when Marat Safin hit his jumping 2-handed Bh, he was shifting his weight forward and driving off his front leg rather than his rear leg. Even tho I've never seen anyone do this for a one-handed Bh back then, I decided to incorporate this. I would not necessarily jump but I would lean into the shot and drive off my front leg to hit all my Bh shots.
This solution worked like a charm. The pain in my L elbow and R heel started to subside even tho I was playing a lot of tennis at that time. In less than 3 weeks, both pains were gone & never returned. Pretty certain that a medical doc would never have come up with that unique solution.
