Spine surgery symptoms and conditions

I've been taking kenalog injections for appx. 2 years, have 5 bad disc, at first it was good for 3 months and now they last no more than 3 to 4 weeks I've turned down the open up and put in the cage surgery, my insurance want pay for this new Laser Spine Surgery, after kenalog what injection do I go to?

I have diagnosed osteoarthritis, two joint replacements, looking at a third, and my knee hurt at time. Bad fall over a year ago led eventually to spine surgery with fushion of several vertebrae. Before fall I had some back pain and have had the shoulder pain for years(and now requires partical reaplacement). I was very active and relatively athletic doing agility with my dog. After fall and sugery for pinched nerves, I have never felt normal. Too much pain all over, fingers still numb, don't feel safe running with my dog. I suffered muscle degeneration due to the pinched nerves. Finally after numerous expensive test etc, rheumatologist suggested kenalog shot if I didn't feel better soon. Also tentative diagnosis of gout but my stomache could not handle pills for gout. So I got a shot of kenelog. - Super! I felt "normal" for the first time in over a year, didn't feel weak in knees, felt I could walk faster and further. Positive side effect was clearing my sinuus' and clearing up cough from phlem from sinus area. Got shot about 5 weeks ago and it has gradualy faded. I do not feel as painedl, but my activity level has decreased. I want another shot.
