Who can relate and share?

I recently had spinal fusion C4-C5 - this is day 4 post op. I am managing pain ok (meds and other PT practices) but feeling waaay more pain at night. Any idea why? The pain is less in my neck (anterior, they went in through my throat) but rather, my pain lives more down my shoulders and arms. The location of pain and numbness in hands and arms is not new, but this has all been lit up FAR WORSE since surgery. Why? Is it that I’m doing too much in the day now that I’m feeling better, Is it that simple? Chill out? Lay in bed instead of bopping around doing dishes and such?

Insight from any of you bendy beauties?
