I'm sorry I don't recall what your arm surgery is about. I do recall reading one of your previous posts on the subject. I don't know as there is really much of anything I can offer with regard to this. You mentioned you've already gotten 2 opinions. If you get another, what you'll then have is 3 opinions. But, in the end, you'll still have to make up your mind as to which one you want to go with. Maybe yet another opinion will be helpful. But maybe it will just muddy the waters further. Of course you won't know until you've done it.

I don't know if you're familiar with it. But PsychCentral has a sister website: "NeuroTalk". (Maybe I mentioned it in a reply to one of your previous posts?) Anyway... you might take a look at the forums over there & see if you see anything you think might be of benefit. There are a lot of members over there who are knowledgeable with regard to a wide range of medical conditions. Here's a link:
