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? Also, is there anything I can do myself to help matters as it's very depressing.
