Oh, my. Nerve damage!
I just had rotator cuff tendon & outer biceps tendon re attached 4/19.
My advice, don't accept the nerve block offered by the anethesist. My arm was totally numb for 36 hours, and now 7/3 it twitches occasionally on fingers 2,3. I don't know if twitching is related, but the pain levels were low enough after surgery I was off the codeine substitute in 30 hours. Had a 2 weeks supply. Less intervention is better I imagine.
Also, medicare paid $10000 for the nerve block and $3800 for the tendon surgery, including sewing up 5 muscle tears. Took about 2 minutes to do the nerve block, hour or more for the surgery to go by how long I was unconcious.
There is more pain now doing some of the exercises to build the muscles up, than the weeks after surgery. Isn't naproxen wonderful?
Last month I bought a farnell.com copy of a go-pro outdoor camera, to put on my bike helmet and record behind me continuously. 4000 lines sharpness they say. $98 with the extra battery & charger. It's loaned out, when I recover it I'll post pictures of my bikes. It Uploads direct to linux/PC, acts like a hard drive out of the UMC port. PN 82-19749. Also comes with aps for apple phones & android.
After 10 weeks I can play Joplin Magnetic Rag, but hurt after that. Before injury I could play 2 hours. I can't reach beyond octave 5 either. Injury was to right shoulder/biceps. Not sports related, fell on a pipe bringing in the mail!@#$#$%^$%&^.
