I am three and a half weeks out from spinal fusion/microdiscectomy and still in lots of pain. Surgery on c5/c6. The most concerning pain is that I feel very achy, almost flu-like. No fever at all (I keep checking it) and my incision looks great. My hands, arms, legs and feet ache most of the time. Still having lots of neck pain as well. I am 43 years old and in fairly good health before surgery. Anyone else experience this kind of achy feeling? Thanks in advance!
