What are the possible causes of concussion?

Hi doctor,

I was out partying last night and had too much drink. I ended up in the hospital and got discharged this morning. I passed out yesterday and hit my head, wondering if it might be a concussion. Please help.

Thanks.

Hi doctor,

Thanks for the reply.

1. I was influenced by alcohol.

2. I passed out suddenly due to the alcohol, and my friends caught me. I threw up many times. When the ambulance picked me up, I fell just outside the apartment and hit my head.

3. I passed out first, and when I was on my way to the ambulance, I fell and hit my head.

4. I have a small wound on my right forehead with small amounts of dry blood.

5. I mainly had pain in my head. When I am not on screen time and close my eyes in a dark room, the pressure in my head starts to feel better. I ended up in the hospital and have read through the summary of what happened. And they were going to do a CT (computed tomography) scan but could not do it since I did not allow them for some reason. I was drunk. So I am just worried if the doctors want to do a CT scan. Could it be just in case, or did they think I had a concussion? They discharged me in the morning and diagnosed me with ethyl alcohol poisoning. I am just worried if there is a concussion or not.

Thanks.
