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.
