schussonyeah because thats exactly how it works. I carry an epi-pen everywhere i go on a paracord necklace i made on for a mountaineering trip so it would use my body heat to not freeze. If you do have to use epinephrine, you have to get to the hospital. it doesnt prevent the reaction nor do anything to mend it. it merely buys you time to get medical attention. if you dont the reaction will continue and you will either die of cardiac arrest from the epi or suffocation from the reaction
For peanut butter? Worth it
Really though, that sucks. A lot. I don't have any allergies myself outside of being mildly lactose intolerant. I have have tons of friends and family who have pretty intense celiac, which is pretty brutal.
Definitely thankful I don't have to worry about delicious, tasty things killing me.
