Oh, I'm sorry. I should have been more specific with his condition. He has a large disc herniation and sciatica in the L4-L5 lumbar region. The pain is in his lower back, left buttock and travels straight down the left leg all the way to his toes. The pain seems to be debilitating and crippling, as he can barely move anymore. He's also mentioned that he's lost some feeling in his leg, and that he constantly gets a numb and/or stong tingling througout the entire left leg from time to time My first post pretty much explains how bad it is.
