Lionel, I am certainly not qualified to address most of your concerns, but I can tell you from personal experience that nerve damage is very slow to heal. I have damaged nerves in various accidents, with the following results dislocated pelvis, severe pain in lower back, numbness in legs and saddle area I think you called it - put pelvis back in place with physical therapy, and over a 6 -9 month period, pain diminished and feeling returned 95% or more Ruptured discs in neck, pretty well broken at the c5 level, pain and numbness in both hands, lost use of one, had surgery, both hands came back nearly immediately cut off one finger, sewed back together, feelings returned over a 10 yr period, about %75 now. Crushed ribs in lower rib cage, tore muscles up, severe cramps and pain associated with it, continues to cause problems 15 yrs later In general, I would suspect since the nerves were not severed, most if not all functions will return my best wishes to you and Win tex
