But he did not tell me any thing more. Could this low
level of testosterone
be causing my headaches? What usually causes a low testosterone
level? How concerned should I be? I am only 21, and I was involved in several blasts while deployed in Afghanistan last year. They say that I received a moderate TBI from one of the blasts. Other symptoms are depression, lack of energy, trouble sleeping, and a irregular heart beat. I don't know if any of them are related.
