After my concussion, I feel my head is full of blood whenever I am angry, lowering my head or even defecating. It feels like I am wiring another hat. Is it real or just my brain thought so? I am not sure if my vessels in the brain are normal or just my brain cannot control the blood pressure well. My blood pressure is actually at the lower end of normal range right now. But I don't know if it is the same in my brain. My MRI and CT show nothing as everybody..

My family has stroke history. So I am worrying if I will get one if things are not right inside my brain..
