I'm a 50 year old female and in good health. Was in bad pain for 1 1/2 years, pain meds and muscle relax. Last Aug I went off everything except over the counter pain relief as needed. (Got a very thick pillow top mattress and sleep only on my back now)I'm sure there is no connection but that is the only change in my life at that time. Went back to my Ortho in FL in December thinking there would not be any changes. He found in 9 months went from 2ish to 2+ suggests 360 degree fusion at L4/5 and L5/S1 -ALIF and then flip me over and MIN to put screws in. Now I've moved to CA and found a Neuro who agrees and to the get it done sooner than later but does TLIF-maybe as high as L3. I've done a lot of research and watched for info on your forum. My big question is I'm seeing everyone is doing these proceedures for pain. Anyone out there heard of this little of pain. Both of these doctors are really shocked that I'm not in pain. Just had a nerve test and have lost very little there. Believe me I'm very happy to NOT be in pain as I used to be but it also makes it very hard to have this kind of operation.
