Last September I developed hives, my GP felt it was an allergy but since then I have had 3 anyphalactic shock episodes where I have had to be hospitalised, I now
carry an
Epipen. I have just seen a dermatologist who changed my antihistamine presciption, and who told me the hives could be linked to my thyroid condition and has taken blood to test for C3, C4, haemoglobins, electrophoresis, full blood count and ESR. Can you explain the link please between hypothyroid and allergic reactions?
