So, here I am again. The right arm is back to 97% range of movement and pain free. This last week or so I’ve started getting exactly the same symptoms in my left arm. I did a search for this thread to see what I’d written and yep, dead arm, weakness in forearm and wrist. Shoulder muscles not engaging with upper and lower arm on lifting etc. Feels exactly like last time only not quite as painful. But then it is early days. I didn’t get diagnosed last time until a year into it. This time I know what it is from the very specific symptoms. I first thought it was a response to slapping. I never really learned to slap and was practicing it again but no, it’s clearly the same as last time. The only consolation is that it’s in my left arm and I’m right handed. Long practice sessions are out for now though.
