It's 3:06 in the morning and I have no car so going to the doctor is not the best option right now. I was at an amusement park, a really shitty ghetto one near Colfax in Colorado(this is just to paint a picture of how ghetto it was for those people who know about Colfax and such lol) and I was on one of the rides and it was going up it jerked forward sending my head backwards into a metal bar I saw a flash of white light for literally less than a second and now my head is hurting like crazy I'm wondering what I should do, I mean I know no one here is really a doctor but concussions are pretty common so I dunno anything to help my troubled mind. Anyways what is the best thing I can do right now and is it okay to take medicine like Ibuprofen or similar things like that..
