About a year ago, I was doing a lot of kayaking and developed a pain in my left elbow. My doctor told me that it was tendonitis (golfer's elbow) and we tried several methods to deal with it.
Ibuprofin and rest - no improvement.
Physical therapy - no improvement.
Cortizone shot - immediate improvement, but not permanent. After a couple months, I was back at full pain.
The doctor at that time felt strongly that it might be my ulnar nerve, but I had none of the regular symptoms - no tingling or numbness in my hand. A nerve specialist did a set of EMG test and found no problems.
He referred me to another doctor who decided to operate. I forget the technical name for the procedure, but he scraped off the scar tissue and sewed some of the frayed tissue back onto the main tendon. This also resulted in absolutely no change in the problem.
But I'm wondering if maybe that previous doctor might have been onto something.
I find that if I'm doing something like washing my hands normally, I get a lot of pain. But if I straighten my arms and then wash my hands, no pain. So I have to wonder if the ulnar nerve is being strained when I have my elbow bent.
