Thanks. Thanks kind of you. Don't know where this will end up now. The docs are confusing me, but they've got me on some good drugs and cleared me to use the left arm normally for now. They think the problem may be mostly in my cervical spine, which is more in line with what all my previous docs have said. MRIs next week to confirm. I now have 2 top surgeons on it working together: a shoulder/knee specialist and a neck/spine specialist. So we'll see what they say in a couple of weeks. I have my knee surgery 12/1. That's supposed to be "simple."
