I've never had your specific problem, but I have had my fingers, hand, and arm go numb on my fretting hand.
I was playing a big symphony concert at the big symphony venue here in San Diego on DB. Before the show I realized my tux was missing so I had to borrow one from my school. The tux ended up being way to tight and it cut off the circulation to my let arm. Half way through the set I couldn't feel the strings anymore, So for about 20 minutes worth of music I had to stare at my left hand to make sure they were even on the strings haha.
I know my story doesn't really help. I just wanted to share. Good luck with getting better, It seems like these guys before me know alot more then I do. So I think you'll be able to find some useful info.
