Hi all, Im new here so Im a little unsure as to how this all works. First off, I

sustained a "mild" concussion in May of 2014 when I fell off my bike. I went to

the emergency room, had a CT, which of course, was worthless, and went home.

I was very lethargic and fatigued for the following days. I had no headache, no

amnesia, no phycological problems...nothing but fatigue really. Two weeks after

the injury, I felt normal, and left my peaceful family home for DC where I had a

summer internship. The first week in DC, I felt about 90%. However, I soon

began exercising, which was one of the biggest mistakes of my life. Walking in

DC's humidity is enough to tire out a Northwestern boy like me, but running in it

is just insane. Approximately 24 days after my injury, I went for a fairly

strenuous run. At the start of the run, my head throbbed a little, but I dismissed

this critical warning sign. That night, I had terrible insomnia. From the following

morning onward (nearly 6 months), I have lived in a perpetual state of

exhaustion/fatigue/whatever you call it. I've dropped out of school for the time

being. I've been to a sports medicine doctor, but he refused to believe that I

could simply be tired and not have a headache; later on, he prescribed me

Amitriptilyn for the head pain I don't have. Now, I am scheduled to see an

excellent sleep doctor, who I hope can help resolve my problem, but I still want

to ask the nuerotalk community for any advice. What could be causing this

chronic fatigue? What can I do to mitigate its effects?
