Welcome to Sr.
Going through a detox facility can be tough stuff, but not near as tough as staying addicted for the rest of your life. It will be touch and go for awhile, and you may experience the back pain again, but there are alternatives to narcotics that hopefully will work for you. I experienced severe back pain about five yrs ago after falling from a ladder while working. I took pain pills in the beginning, Vicodin, then Percocet, but became so goofy that I couldn't remember when I'd taken them, so I popped more than prescribed, which made me even more goofy, so I finally asked my doc to put me on something else. He prescribed Ibuprofen, but they tore up my stomach, so I just went cold turkey off all of it and decided to strengthen my back. I started exercising each day and soon my back was able to handle work again and it's been fine ever since. My answer was exercise, but yours may be a totally different combo of remedies to improve your back condition. I applaud your resolve to get healthy and would suggest considering exercise, even in limited amounts as a means of strengthening your back, however I am not qualified to advise you in any way. My experience may be totally unequal to yours, so a trip to a back specialist may be worth the expense.
