I believe the doctor will tell you it isn't from your mountain biking and all that stuff. It comes from all those times you locked yourself in the bathroom as a youngun'[8D]

OK... Ok... seriously... ice and more ice and Motrin etc. I got it in an elbow once. I let it go so long it finally got bad enough I couldn't hold a glass of water with that hand. I finally ended up getting a series of ultrasound therapy along with a heat, exercises and then ice. It cleared up in about 2 weeks. The next year I got it in the other elbow. I didn't wait for it to get so bad this time. One week of treatments and I was good to go.
