I had a one level fusion at l5/s1 feb 22 of this year. I'm having weird sensations in my upper lumbar region to lower thoracic region. Its the weirdest thing. Almost like hardware was put that far up although I know it wasn't. It also hurts more higher up then at the spot the fusion occured at. For other one level fusions at the spot I hd mine, what was ur back experience like? Where did it bother u the most? Thank u all in advance. I'm 25 days out of surgery, walk a lot and wear a back brace except for when I'm sleeping, showering, or laying down.
