woah man that sucks - vibes to you....
Sounds like some serious surgery right there though, and just wondering, could it be the actual surgery that fucked nerves, not the block? I broke my collar bone, and although i didn't have surgery on it, when the bones started to regrow, into a large callous bone area around the original break, it put pressure on my C6 nerve (i think it was C6, might of been C8.....) anyway, i never noticed but i kept dropping the toilet lid and stuff... and couldn't figure out why.... basically the nerve had been damaged and my left thumb wouldn't work from the knuckle up, i had no reaction to force from it, was totally weird.... i did eventually heal back up and work again, but nerves take AGES to heal because when they die, they regrow from the top down, and it's like a cm a month or something.... so hopefully it'll all return to normal, but might just take ages.....
It is the worst feeling ever though, being able to touch your toes and move them around with zero feeling, they're just like bits of meat!
