I'm sorry things are so crappy for the two of you and I hope your solutions come soon.
I have had back pain since 1977. I apparently have a fracture thats not operable without serious consequences. I have chosen to not take pain meds (addiction has been in my family long before RAS) the reason for my explanation of me is that I sympathize with your husbands pain. From what I've read your husband has a buldging disc? My husband was in a motorcycle accident which gave him a buldging disc, chiropractor, time and b-complex along with believe it or not bayer asprin have been doing wonders for the disc. Just thought I'd share this, sometimes its the simpilest things that can fix.
good luck and I really hope he feels better soon
