Mrs D makes a good point...Elavil (amitriptaline) does increase the lightheaded feelings so it's possible it wouldn't be appropriate for you to take it because of the fainting. She makes a great suggestion for you to take the info. with you to the neuro. It's not for everyone, and it is no fun to come off of even at low doses. It's not going to "fix" you in a hurry, but I do believe it has given her some relief.

My daughter had regular concussion symptoms for about 1 month. Then she felt better for awhile, then she started pushing herself to get back to exercising. After that she became more sensitive to triggers and had some really cruddy months. Her cognitive issues, especially, seemed to get worse at that point.
