i'm sending a link to this thread to one of our members here. she is the nurse on the care cure forums. the link to that site was already posted on this thread, but i will post it again. it is for spinal cord injuries. it is a very active board.

there is a forum there for newly injured. it can help you get the right treatments. plus loads of info for family.
my thoughts and prayers are with your son bob and your entire family.
