Right elbow to right wrist..
I've had severe bicep tendinitis in right elbow/forearm for a long time. 2-3 weeks ago, over night, woke up with skin numbness palm side of mid rt forearm and when I extend arm at elbow SEVERE burning about 3" above thumb side of rt wrist all the way to wrist.
Burns like SIN and takes 30-45 seconds to ease off.. If I tweak it bad enough, forearm aches deep for several hours.. REALLY getting to be a pain in the ass and is affecting everyday activities and the deep aching effects sleep
I thought I had a trapped antebrachial nerve. Doc (GP) said today it was tenosynovitis..

Prescribed a round of steroids

and exercises (a couple I can't even do).
He seems to think I have abused my body. I think getting old sucks physically.. haaaa
