My POIS cycle is always 6 days long. However, about two weeks ago, on a monday, I entered a cycle. On thursday, (day 3 or 4, depending how you look at it) I injured myself at work. I bled quite a bit, and I felt a burst of adrenaline. After the adrenaline wore off, I felt great, no POIS at all.
Just curios, is there anybody with severe allergies who has used an epi-pen in POIS? If so, did it relieve your symptoms?
