I have a mild allergy to most biting and/or stinging insects (nothing major, the bites just swell more for me than for other people), but an extreme allergy requiring epipens for bees, wasps, and hornets. I assume also spiders, but I am not certain on that.

There is also an allergy to the adhesive in tape/bandaids that runs in my family, I’m lucky in that mine is mild and takes somewhere around a full day before anything happens. My cousin however has a note on her medical records stating that they cannot be given band-aids or similar by the hospital because (if I remember right) she gets blisters, and it’s a relatively quick reaction.
