I have fatigue, headaches, and abnormal body? from Running?

Question:I got all these sickness after the week of running hard as possible. Is it possible? I have been running for 7 years now and its going to be a year since i started these symptoms. I hated and been to doctors over and over again with no answers. With my head, i get headaches and alot of times like there water or liquid trapped in my head and hurts when i move to fast. When i try to run i get tired really bad, and can't run because i dont feel like it. During the days, i just want to sleep because it seems like i missing something from my body, my arms, and legs don't feel the same.
So i was wondering if i am the only one like this? Or any one have any answers or solutions and even opinions would really help. thanks

Have you had a blood test? I had this problem last year, after having been a runner for about 8-9 years. I ended up having aplastic anemia, a VERY rare bone marrow failure disorder caused by exposure to environmental toxins (in many cases).
