RyGuy,

Welcome to NeuroTalk.

First thing, you need to start wearing ear plugs. They will cut down the high end of noises. I like the cheap yellow foam cylinders. Air tools can be a problem for anybody's ears. Also, get your upper neck checked out buy a specialist in upper neck injuries. You may be exacerbating an upper neck injury when you look up causing the stumbling.

It might help if you slow down your movements, especially when you need to look up. If you work as if your neck is injured and you need to move it slowly, the slower movements might just solve your problem.

You are still early in your recovery from such a trauma to your brain, skull and neck. Take it slow.

Let us know how you are doing and anything we can do to help.

My best to you.
