whatfur,

Welcome to NeuroTalk. Sorry to hear of your fall and concussion. I can remember the risk of trying to keep my hands warm while being on a slippery surface.

It sounds like you may need to have a therapist try the Epley Maneuver to see if it will resolve your dizziness. There is a YouTube video that may help you do it at home. The goal is to get particles in the inner ear to move to a place where they do not cause dizziness. these particles can get knocked loose by the impact.

If you have other symptoms, let us know and maybe we can help you.

My best to you.
