C&F,

Welcome to NeuroTalk. After 2 CT Scans, it is highly unlikely you have anything serious to worry about. Your symptoms are not uncommon.

The itching can be due to some injury to the nerves in your skin or between your skin and your skull. Itching is commonly the sign of nerves as they re-establish communicating with the brain. I don't think you should be worried at all.

You may have subtly injured your upper neck and now a bit of inflammation is causing some of your symptoms. Icing the impact spot and you upper neck may help.

I suggest you plan on making your trip home in stages to reduce the risk of fatigue.

My best to you.
