I'm back! It turned out to be dehydration. They gave me liquids.. my arm really hurts. The reason I thought it was Smoke or Carbon sickness was that the headache was starting to really hurt and feeling weak. Some website listed the symptoms. After a blood test, they suggested liquids. All better Weird cuz I did drink a lot that day, but also did a bit of sweating. Careful this summer.
Thanks for replies!
I recommend.. amputation!
