Hi Clemente and welcome to our little brain boo boo club.

I was a fitness freak before my tbi and was frustrated that the headaches stopped me from working out. I mentioned this to my PT and he suggested that elevation in my heart rate trigger a blood pressure spike which made the headache go nuts. We exercised together in the gym until I found the range where I could elevate my heart rate without worsening my headache. I now where a heart rate monitor during physical activity.

I hope this info might help.

Cheers
