I've suffered for 15 years with lower back pain. I've tried everything under the sun with no relief. My only remaining option is a multiple level spinal fusion. I'm trying my best to avoid that.
A couple of years ago, someone recommended a mind over body book to me. I thought they were crazy to even insinuate that my pain was more mental than structural. I've got several MRIs to prove my degeneration. Out of sure curiosity and after hearing that Howard Stern, the radio guy, claimed Dr Sarno had changed his life, I read Sarno's book, Healing Back Pain.
He makes some interesting points and he has given me pause before I have any surgery. It's only a few bucks. You may want to read his book.
Anyway, I know exactly the pain you're experiencing and unless you have this problem, there is no way for others to sympathize. I wish you all the best.
And, oh by the way, make sure you apply for VA disability. It's your right as a vet and the American people owe you for the damage you sustained to your body complements of your high G environment.
