That is how I was injured too...got My skates pulled out from under me by someone and my head bounced a few times (with helmet). 15 months ago....it can be a long road back but there is progress. It sounds as you are still in the acute phase. Rest, rest, rest. Dark rooms, no running, etc.

Lots of advice here on good tips.....neuro opthamology is very important. Vestibular therapist?

It does get better slowly but it is a difficult road. Hang in there. You will make it.

Ps. Santa brought my kids an air hockey table and I can play a few games. This is great progress!
