question: After sitting on the toilet the other day, my husband (60 y/o) stood up, legs went numb, and he fell backwards and broke the toilet tank in several pieces. He was in a minor car accident a few wks ago and either fractured or broke a vertebrae in the top of his spine (medical team is undecided). He has never had this problem before the accident. However, after showering yesterday, he almost fell out of the tub but caught himself with the soap dish handle. Could these falls be related to a nerve in the damaged spine area?
