since you have not had sea food chances of allergy to sea food are there if you take it not knowing the food allergy status. hence i suggest you to avoid sea food and take other sources of omega 3 supplements like walnuts flaxseeds hemp oil soyabean oil and pumpkin seeds. 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 doctor. i sincerely hope that helps. take care.
i don't eat seafood. should i be taking omega 3 supplements/vitamins or should i get it from another source such as walnuts?
