Like many people i put a chemical on a wound located on the bottom lip, produced unintentionally by a bite, to heal it and that trigger EC.
Before that i never heard or knew something about this condition and honestly i feel stupid, ignorance is a double-edged sword.
So in my case is not related with some alergic food.
I have lack of confidence on unnaturals things like aquaphor e.g. and more before visits to dermatologists.
