I had surgery on L4/5 ! I had a spinal fusion,herniated disk etc... Now I had this surgery Aug 12. For the last week a and a half I get really weird back tightness,tingling etc. When I wear my back brace and take it off it still feels like its on. It kinda feels like my instruments (rod and screws) are going to poke out. This is so hard to explain. I get weird sensation and i become uncomfortable. Does anyone know what i mean???? I feel like something has shifted. Maybe I am losing my mind!!!!
