My 2 cents worth. Stay clear of Pain Clinics. Florida has finally starting coming down hard on Pain Clinics. The sad part is there are people who really need help with pain managment that now has to do without. Even local Dr tell you right up front or a sign on the door, No pain managment.
You need to find a neurologist, The VA has these Doctors.
Another thing to try and your hubby probably wont, but EFT by Gary Craig is one program that will get rid of pain, guarenteed. The problem is We dont want to do it for some reason, and I think its because we think we have to have medications. EFT has a free manual and its worth a read and a try. You might have to try it first then maybe he will. My son has diff pains, and he rubs the "sore spot" and I do all the tapping on my own acupuncture points and saying all there is to say. That also works. You need to get comforable with using it first.
My grandson got rid of a terrible sunburn and he actually tanned up
My granddaughter is now using it for TMJ. Its so neat and so easy, I dont know whats wrong with us people that refuse to use it. I use it for pain anytime I get any sort of a pain, I am right on it. By the time I am done (2 or 3 minutes) my pain is gone, or if a little is left over, I will do it again. EFT is free, dont fall for people trying to sell it.
