My husband is limping, right leg and right foot cramping, numb, continuous pain, can barely stand or walk far, completed physical therapy has had problem since he passed out while driving and went air born and rolled severel times. Still no explaination why he passed out. He has seen an orthodedic & neurosurgeon. 1. What caused him to pass out? 2. Why is he still limping and in pain 7 months later and physical therapy no relief?
