Although I'm 41 and by your standards (older than you lol) but I have something to say.

Rsd/Crps can have these affects on the brain, my concentration is not the same especially during "flaring" it is most definitely affected.

Depression?...just par for the course and should be expected when dealing with life altering chronic pains.

I honestly don't know what's worse, getting shocked from a damaged misfiring nerve, or getting burned badly from the Allodynia, their both equal I think.

At least you've come to a great website for support and info and people like yourself.

All the very best to you!
