Update on life:
My left arm is healing nicely. After just six weeks, the swelling is going down and the incisions are closed. It remains to be seen how much use I get back. Six weeks of non-use coupled with multiple sclerosis makes a muscle not work. It is possible I will gain some use back, but not 100%.
That's okay. I knew going in I had a limited chance of regaining use. Without the surgery, I had a dead arm. It could no longer do anything but get in the way. Physical therapy starts today, three times a week for six weeks. Then we can evaluate how much will help us.
As for the wrist, it is still swollen, too. The carpal tunnel surgery seems to have helped, but the arthritis is causing some issues with the joint movement. It seems I do not get to go without a bit of work to make it better, too.
