Newbie question, meds v rhyzotomy

[diver110]

I have had back trouble for 40 years (i.e. since I was 19), but up until about a year ago I was able to manage it with massage, yoga, and chiropractic. Then things took a dramatic turn for the worse, at one point putting me in the emergency room twice in three days. I then went through a fairly intensive persiod of physical therapy and massage therapy which improved me perhaps 30%. I also tried prolotherapy, which did nothing. I also tried a decompression machine at a chrioproactor. Also did nothing. The pain is in the L3 area on the left. The range if 0-4. I can actually manage it pretty well with vicodyn. The question is whether I should try a rhyzotomy, or just stay with drugs for now. All feedback appreciated.
