If you are interested in chiropractic, why not go see a chiropractor for a consultation? You don't have to go through their course of treatment if it seems like it won't help. Also, another possibility is to look into acupuncture.
I am a firm believer of chiropractors. They are specialists in muscular/skeletal system and have had to go to years of schooling, including medical schooling to perform their skill set. I recommend seeing one!!
This damage you have is not repairable by chiropractic. Unfortunately. The best plan of action, provided you gave accurate information, is to get an adequate pain management by specialists, do special back gymnastics and if that doesn't help enough, the last resort is an operation. Good luck and get well soon!
