Glycerin allergy



I have been told by an allergist that I am allergic to glycerin. I don`t seem to have any symptoms that normal allergies give but I have had headaches for 20+ years. Could the headaches have anything to do with allergies? I am also allergic to pork products which I think is why I`m allergic to glycerin.


It is possible to develop a delayed type hypersensitivity reaction to glycerol confirmed by patch testing.  There is a relationship with headaches and upper respiratory symptoms related to "allergic rhinitis" and "non-allergic rhinitis".  I am not following your rationale regarding pork products and glycerin.  I know of no relationship.  I would see an allergist experienced it these unusual issues who can help you better understand the problems you are experiencing.
