Peripheral nerves will heal too once you take the pressure off them - just very, very slowly.
At the risk of saying the wrong thing - do remember that you've been known to ask for too much too soon from your training - and allow for the possibility that it's the same with your PT. I'm sure he's giving you work that will yield results over the long haul - as in months to years, not weeks. I've read where it can be a year before someone even notices improvement when nerves are re-growing from a significant injury or surgery - but it's super important to keep the muscle and circulatory pathways open to let the nerves regrow, and to let the limb function properly when they do. It's sooooooo easy to get discouraged when you're not seeing immediate results ... not to mention bored with doing the same exercises day after day.
Hang in there kid.
