xoe,

Do you play a contact sport? This is a serious matter. Your brain needs lots of time before you risk any kind of repeat heat trauma, if ever.

You should not be exercising to a level that causes a return or increase in symptoms. Start very slowly and stop before you feel any symptoms. The next week, try a small bit more intensity. Take it very slowly. Every time you cause a return of symptoms, you have delayed your recovery.

Rest, good nutrition, low stress.

My best to you.
