I am 21 years old. I have anger management issues. When I get very angry, I tend to hit myself mostly on my head.I don t hit myself too hard, but whenever I hit, it causes me a headache for a day or maximum two. I don t do it often. But whenever I do it, I have a headache till the following day and then I feel fine. I hit myself even yesterday, the pain hasn t gone yet. I am very worried that it s causing some problems internally and I m not aware of it. What i have been doing, is it dangerous to cause any problems to the brain or any other part? How can I be sure that I don t have any problems? What tests should I get doctor? Please help.
