It sounds like you do have a fish or seafood allergy
. We can develop different kinds of allergies as we get older. I had a pt one time who loved seafood...never had any problems with such...one year for her bday..she went to a seafood restaurant...and had an almost fatal allergic reaction
to seafood. She was saved by an epipen
Sounds like you have some form of an allergic reaction to seafood/fish. I would try taking some benadryl
and see an allergist to see what they think.
