Well I had my surgrey like a month ago and I would have pain in my trapeizus muscle (which I figured out it was because of my head position) but like a nite or two ago I was trying to fix the way I was lying down and I heard a crack in my neck(around t1-t2) now it's a little pinching from time to time its like a mixture or pinching and soreness on my bone/muscle

What could've happened? I don't want to worry my

And also from time to time my
Left shoulder would tense up sometimes causing like a burning sensation (it was also like that before the surgery)
