I slipped & fell on my camper steps & broke L-1, L-2, & T-12, on thurs Aug 8th. Came home from hospital that Sun., with dr.s orders to do nothing but rest & walk as much as I can tolerate, while in the hospital a PT showed me some exercises to do in bed, I wonder if there are any more exercises is should be doing, I did not receive a PT referral, shouldn't I have?
