Hello, I had ALIF on L5S1 on Oct 20, 2015. I am just about 4 months post opp. Should I still be having low back pain? Both sides of fusion.I thought at this point I would be doing much better. My abdomen also gets really tight around the incision, like a fist clinching and sometimes I feel bloated from it. I starting PT at 6 weeks and was given new stretches at 3 months. No sign of fusion from X-Rays yet. Two days ago had a new MRI to see what could be causing back pain. The DR said MRI looked good and it was probably inflammation or the fusion wasn't too strong yet. He wants me to stop PT and start taking Ibuprofen when needed. Is this normal at this point? I am worried? I will have CT scan at 5 months. Thanks for any advise.
