hello! I had an XLIF at L4/L5 13 months ago. It partially fused but my hardware is loosening and I’m in tremendous pain. I’m 23 and otherwise healthy. However I’ve noticed that being vertical AT ALL causes the worst pain. If I lay down, the pain is still there but the pressure and intensity calm down. Does anyone else experience this? I can wake up almost pain free and then 20 minutes after sitting up or standing and the pain is severe.
