Hi,

I have had fainting issues for the past five months (am a year post concussion), and had a fluctuating blood pressure. My neuro told me to increase my salt intake, eat regularily and to have snacks every 2 hours.

It helped for a bit, but I have also found the more active I am, the more I get dizzy, black out and faint. I can get dizzy from laying and then standing, or just from sitting to standing. I also find that the more dizzy I am, the more vertigo I get as well.

I had a big concussion when I was a teenager, and I would faint down stairways and smash my face on desks, or just fall on the floor. They resolved after about a year, but it is still an unnerving time.

My neuro also said that the concussed brain has a difficult time controlling the blood pressure and it should resolve in time, so its best to have the salt and good nutrition.

Good luck!
