So recently (3 days ago) i was in las vegas nevada and took a spin on speed.

I got on for a second time in a row. That is what caused problems. I rode in a different seat and hit my head many more times on the restraints. Plus i felt the G's were much more forceful. After i got off i had a severe headache and nausea. After that i didn't ride anymore for the day. We then left las vegas and began our drive back to NM. I was tired the whole drive and we didn't do anything besides stop by nascar cafe. THe nausea and headache lasted for the next 6 hours but then went away. The next day i was still nauseous, had a bad headache, and was lightheaded. It has lasted since then till now and was wondering, do you think its possable that the roughness and the G's gave me a minor concussion. Im not sure and on all the other rollercoasters i have been on i have never experenced anything even close to this. If it is really a concussion its grade 2, in which there is no blacking out but symptoms last longer than 15 minutes.
