Tendonitis again?

Seems like it's one injury or another, but who ever heard of ischial tuberosity tendonitis? It's tendonitis of the sit bone or more commonly called a pain in the ass. It's actually inflammation of the tendon attachment of the hamstring to the sit bone. Just when I thought I had experienced every running injury possible, I come up with another one. The cure is the usual RICE or rest,ice, compression and elevation. I'm not sure about how I can apply compression to it although squeezing into some butt hugger jeans might do the trick.
