What do CT scans show?

I had severe muscle pain yesterday and today mainly in my neck and upper body, so bad I couldn t move. Couldn t turn my neck, couldn t lift my arms, so I went to the ER. They wanted to give me a CT scan and said it was mandatory. I got it done and after about half an hour later, they said it came back normal.... show more I had severe muscle pain yesterday and today mainly in my neck and upper body, so bad I couldn t move.

They wanted to give me a CT scan and said it was mandatory. I got it done and after about half an hour later, they said it came back normal.

What do CT scans even show? If I had cancer, would it show? Does it show inflammation? They told me it was mostly muscle spasms or multiple pinched nerves.
