I've severed a nerve in my thumb once, it was all nasty. Nerves look like little white worms they're all slimy and smooth.
I haven't even been alcohol swabbing, just pinning when I get out of the shower. I hit 1.3cc's of prop today, most prop I've ever done at once. My bp went up just watching my bro play COD4. Workout was nice, I've been hitting it hard, time to recover for a week or so. I am a clean person and I use only fresh terumo pins so I'm not worried about infection with this AP gear like I was with some other brands I've used.
