I got this gizmo when I had it bad from swinging a hammer. (I've heard of way more tradesmen getting it than tennis players. Why isnt it called carpenter's elbow?) Anyway. This doodad worked like a charm after a few weeks. You dont even notice it after a while. Cleared it right up, havent had a problem in years. The hard plastic works way better than the cloth or elastic things, trust me. They deform andvall8q your muscle to damage itself more. Plastic doesn't.

Decades of bad ergo and gaming have done in my arms, elbows, etc. The wrap thing below doesn't prevent or fix the pain but completely negates the pain when used in painful positions. So if you can't or won't fix the ergo, get these. I sleep with them even.
