Thie symptoms were just a sudden feeling of not quite feeling right around 2 mitutes after the pin was out of my ass. Then they got worse, a general feeling of ill ease, then light headed, rapidly getting worse to the point of almost looseing it, I was passing out after around 5 minutes. Epi pens are prescription epinephrine(sp?) preloaded shots that are used to treat this kind of shock. A doctor must write you a prescription for them. I will be sure to have one around from now on.
