Golfer's elbow sucks. I've been battling it for 18 months now. Although it has been painful at times, it's never been so bad that I couldn't still do the things I love, like ski. Unfortunately, that has also caused me to ignore it for the vast majority of the time. Only about two months ago, did I really start getting serious about getting rid of this. My medial epicondylitis started after changing my workout routine to include pull-ups every day. After about a month of this, my elbow didn't just hurt while doing pull-ups, but was sort of a continual dull ache, I also was skiing, playing golf and playing tennis at the same time. Despite the term "golfer's elbow", golf seems to irritate it the least so don't think just because you don't golf, you must have something different.
The rest is my opinion....but I have spent a ton of time reading about this subject. You might want to google tendinosis, A lot has changed in how to heal this is the last few years. Unlike tendinitis, the typical RICE (rest, ice, compression and elevation) routine does not always work. The problem is the tendon isn't inflamed, it's completely ignored by the body. Thus, the tendon is not getting any nutrient rich blood in order for it to heal. The advent of PRP was to address this very issue, There are a ton of other treatments that have now sprung up based on this theory. There is shock wave therapy, dextrose injections, even nitroglycerine patches. Hopefully you can cure it by simple stuff such as the Theraband. (I have the green and red) but I wasn't able to. I have been using deep massage with a Theracane (totally different device from the Theraband)) for the last month and have reduced my symptoms by 50%. ,I have my first dextrose injection on Wed. I am hoping in the next month I am able to eliminate the pain for good. I'll let you know how that goes.
