@predictable Good evening Martin I have the same back problems as everyone here plus a L2 fracture in 05 it now has my whole left side worse including burning nerves . About 5 yrs ago I also have bone on bone in my thumbs the rheumatologist then injected my left thumb with hyloronic acid it still doesn't hurt I don't know if they can put that in the back joints but it would be wonderful if they could. I just had a cortisone injection in sacroiliac The Dr. wants to give me one in my arthritic knee also for my muscle spasms on left side of back trigger point injection its lidocaine . Waiting for referrel to come through I wonder how long that will last .
