So I am at 5 weeks post lumbar (S1-L4) fusion and my biggest issue is overall achiness. It is in the morning and then towards the middle of the day and gets worse as the night goes on. I think the achiness in the morning is from laying flat and having a hard time moving in the temperpedi. But I am starting to think the rest of the achiness is not part of recovery but just atrophy from laying around. It is everywhere..upper back, shoulders, lower back, scar area, hips, thighs...AHHH.
