You need to rest it. Get you one of these braces
Band-IT
Probably cheaper on Amazon
I cant tell any difference in the black ones and the white ones.
I ruined mine bending miles of large hydraulic tubing pulling on
a hand bender. When the muscle fibers started to tear loose from the bone, It hurt like hell to try and lift anything. Had to learn to fish left handed for a while. The cortisone shots help for a while. I wear that brace anytime i’m going to be doing a lot of casting or lifting heavy stuff.

If you get one, pm me and I’ll explain how to adjust it.
