The hives I get from some antihistamines aren't an allergy? Ok, thanks. What's the technical difference between an allergy and a sensitivity when you're talking about stuff that isn't life-threatening, only annoying?

This is predicated on my assumption that that antihistamines aren't protein-based; as far as I can tell, they aren't, but that doesn't mean they aren't for sure. You could be allergic to one of the binding agents in a common prep of those antihistamines, rather than the antihistamine itself. Hives don't always mean allergies; I get hives from touch if I don't dope up on antihistamines.

The difference is in exactly what's happening, and how it's treated. An allergic response is a specific series of events involving your immune system. The symptoms can be very similar with a sensitivity, but the standard anti-allergen regimes won't work.

Apologies for my long-windedness and general incoherence. I just got up and haven't had any tea yet.

Thanks, and no need to apologize! I learned something new today.

Hee, you're welcome! I'm currently dealing with dermographia (UGH UGH UGH) so I'm the local expert on Crappy Non Allergic Hives.
