Numb,
Do you have a good "RSD" doc? A neurologist, or someone who is trained, or learned in this field?
That's a first.

I'm not so sure about breasts, since I"m a guy, *edit*

Have you ruled out "TOS"? Thoracic Outlet Syndrome?
That's a very painful thing, to do with the brachial plexus, neck, arms, hands, and is often accompanied with RSD, due to Auto accidents. (That's how I got mine, and Dr S in Philly told me all about it).

So, while you're looking for RSD in those area's, check for Everything!
Have RSD, and TOS ruled OUT!

It's imho, the Only way to proceed....

PM me, if you wish.

Pete
