I've been researching tennis elbow quite a bit now... From what I understand, what you're looking at is golfer's elbow. Tennis elbow is on the upper/outside of the forearm, golfer's elbow is on the under/inside of the forearm.
This is really bothering me. From reading some golf forums talking about it, it sounds like a lot of people have it much worse than me. But I need to get a handle on it.
I found (through the forums) the
Super 7 Exercises for Tennis Elbow. Basically some simple stretching and light weight forearm strengthening exercises. So I'm going to try to go through those a couple times a day. Also thinking about adding turmeric supplements to my daily regimen as a natural anti-inflammatory.
But the stuff I read on the golf forums it scared the hell out of me to the point where I realized I need to take this seriously. It's not going to just "go away" like other various aches and pains.
Getting old sucks.
