Is it shock that cures it, or the epinephrine shot?
Good question, perhaps the epipen alone altered some kind of hormone imbalance or all of the steps combined in that specific order did it.
1) Extreme high exposure within a short time frame
2) Anaphylactic Shock
3) High dose epinephrine within a short time frame
I think we will never know until a researcher starts experiment with it. It's a dangerous technique. It was more of an accident, the question is whether this technique is valid for POIS. I remember he told me that he used 2 epipens, no idea whether that is relevant or not.
