climbing mag article re: elbow tentonitis
2 months later this is actually working for me........
And yeah, I've had tendinitis before....... both elbows, both shoulders. Beginning of this year I got full on freaking elbow pain and weakness like I'd never before experienced.
Haven't climbed more than 10 days this year, haven't lifted since Feb, gone through 3 months of PT including deep tissue massage and finally got a cortisone shot this year.
The RICE, sleep with arms straight, do pushups and wrist curls stuff was no longer on the table for me, cause it didn't do any good. This is the only thing that has helped, other than a temporary relief I got from the shot in my elbow.
So if you have it bad, you may want to try the gig in that nytimes article.
