I am 82 with chronic back pain all the time. Started taking glucosamine+chondroitin a month ago and feel no difference. I have seen 3 surgeons. 2 of them said my back bone looks great and no surgery needed. 3rd saw something suspicious in my neck. Had MRI and CAT scan of neck and definite narrowing of spinal column. Doctor said surgery will not help back pain but will help my dizziness and fine motor skills. I will have neck surgery on C4 C5 and see what it does.
