What can I do about this? (Read details plz)
I went ice skating with my friend, and took a moderate fall. I was in a lot of pain, and my leg was really bruised. Then I went to the mall after that, and felt ok, but I was still hurting. But then when I came home, I played 5 minutes of basketball, and had the WORST. HEADACHE. EVER. It hurt like crap!! I was just sitting on my driveway for like 5 minutes trying to get over the pain. When I cough or laugh, it hurts even more. This happened like 5 minutes ago, and my head feels a little bit better, but still does hurt. Also, any time that I do sudden movement (standing or sitting up fast, lying down suddenly), I get it again. Also, I still can fully function (unless it is painful to do so) physically, and can DEFINITELY function still mentally.
Will this be temporary/how long will it last? Why does it hurt when I do this? How can I get it to stop? What's other information that I should know?
