Just as a side note, i seriously damaged some nerves in one of my hands when i was young, pretty much couldn't operate it for months, and still get the odd tingle now. As long as you stick to PT, and don't believe yourself fixed until your actually told your fixed (been there, done that) you'll be fine.
