I posted this in a different forum but someone suggested that I take a look at this one. So sorry if you are reading this again I am just trying to see if anyone is still having similar issues over a year post injury.

Thanks!

I have had post concussion syndrome since July 2010. I was in a car accident and have been a mess since then. I am 27 years old and had a history or prior concussions from sports in high school. I tried to go back to work, but I just could not handle it. My short term memory is horrible, I have bad headaches if over stimulated, depression, anxiety, dizziness, and problems concentrating.
.
My biggest issues are over stimulation which I am learning how to control and I have major exercise intolerance. That is my main question does any one else here have exercise intolerance? If I do even the slightest bit of exercise such as a slow quarter mile walk, or sweeping the floor, or climbing up the play set to help my daughter I immediately get a severe headache, nausea, extreme fatigue, and sometimes excessive sweating. Once this happens I feel horrible for one to two weeks.

The doctors I have do not know what is causing this does anyone else have these problems?
