chronic pain
"It helps.  I need 2 in the AM to function without serious pain issues.  Later , if I am hurting, I take one more.  It gets me through the day. I get an Injection about every 4 mos.   I'm 78 yrs old and in good physical shape ( not over weight, etc.) I had 2 operations about 2 years 16 years ago for spinal stenosis issue.  I was litrerally crawling up the stairs to my home and in excruciating pain.   2 operations later, I was out of pain for a few years.  
The lower back pain came back a few years ago; MRI disclosed 2 spondys in my lower back  (L1-L5). Three neuro surgeons agreed that I needed a total back re-construction ( 10 screws and 5 rods);there was no  guarantee that I would be out  of pain.  I did not agree, found 10/325 and it works"
