Sorry bud, I understand the feeling all too well. Military life was my big downfall. 80lb packs don't seem to be good for the back. Nor does helecoptor fast roping with said pack on.
I lived with it after I got out of the Marines until 2002 when I was hit by a snowmobile and crushed a disc below L4. Went to the hospital on a backboard on valentines day while my soon to be bride watched me "try" to use a bedpan! I broke two ribs but was lucky my back didn't break.
Was told to avoid going to a chiropractor. After a week, I couldn't take it anymore. I found an oldschool one (like someone else mentioned). I crawled in but I walked out. Felt like dancing. Even found a spot in my mid back that had been out for over 10 years. I asked about the inversion table but was advised against it. They did recommend going to something like a pullup bar and simply hanging without using the arm muscles. That helps.
I only carry my wallet when I go someplace. I get out of my truck, sit down at work or anyplace else, I take it out of my pocket. Tobacco can is another bad one!
