I'm so sorry to hear you are still struggling through all this.

As for heat and potential post concussive syndrome, this is one of my BIGGEST triggers. My previous neurologist tried to tell me that they couldn't be related and that I was just imagining it. (Needless to say, I found another dr.)

The concussion clinic I currently go to has been wonderful. When I asked about the heat, they said that people with head trauma often have the blood flow to their brain effected. This can lead to feelings like hot flashes, being extremely cold or an inability to regulate temperature.

So if you were still having some symptoms and over did it with the heat, maybe your brain is no longer as equiped to help your body endure such high temperatures and activity, due to a blood flow problem? I have no idea if this is the case for you, but it seems to make sense based on what my dr. told me yesterday.

Hope you are feeling better soon! You aren't in this alone.
