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..

If your MRI and CT are both clean, it would mean you have not had a bleed or other CVA (Cerebral Vascular Accident).

The temporary rise in blood pressure from anger and straining could make your head feel 'full'

Learning to recognize this and respond by calming yourself to lower your blood pressure can be helpful. Having a blood pressure kit at home will allow you to verify this temporary increase in blood pressure.

The injured brain often has a problem controlling blood pressure. The lowered head position will increase BP a bit. Many of us have problems with head lowered positions.

Controlling anger outbursts is important. The propensity to outbursts of people with PCS is common but not impossible to control in most situations.

So, don't worry about having a problem in your brain. Just learn to relax when this happens.

My best to you.

I don't know what meds you are currently taking that may have constipation as a side effect. All kidding aside, my MDs prescribed stool softeners for just that reason with some of the meds I was taking. Any exertion that may cause strain may effect blood flow. Not a popular topic, but there it is.
