I got elbowed pretty hard in the forehead - could I have a mild concussion?

I have a wicked headache ever since and my vision is a bit blurry. I guess one really can't do much about it afterward.
Answer:
The same thing once happened to my mom. She ended up in the hospital, there was only a 50/50 % survival. She pulled through, but the left side of her body doesn't work. My advice; GET IT CHECKED!

Any hit to any part of the head can cause a concussion, seek medical attention asap

Yes, it is very possible, DO NOT try to sleep, if you do you could go into a comma, unless your doctor says to, you should get medical attention, very soon!

---

Yes it is quite possible. You should go to the doctor. Also, see if your eyes respond to light, thats one of the best ways to tell, although, as I said, you should still go to the doc.

Signs of a concussion usually do include headache, blurred vision and even nausea or vomiting. It is always a good idea to have a doctor check you out after a head injury, especially if you are having problems. In reference to your last line, it's better safe than sorry, and you don't want to let something go to long.
