Arm rash after eating salmon that had a pineapple marinade

I had dinner out tonight and 30 mins after eating it my arms broke out in a measle like rash. I read online that the marinade includes pineapple juice. I have a history of an allergy to pineapple and orange juice mixed together but I have always been able to have each separately. Any ideas or has this happened to anyone else? Thanks!

Hello,
From the symptoms it looks like a food allergy. Avoid using any lotions and creams for the meantime. Use a mild cleanser with moisturizing properties like Cetaphil. Also use cotton clothes and change the clothes twice if there is any increased sweating. Try keeping the skin free of sweat as far as possible. If the symptoms still persist then you can apply mild steroid like dermacort. For the itching antihistaminics like Benadryl or Claritin can be taken. If the symptoms persist then please consult a dermatologist as steroids may be needed.

It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your dermatologist. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
