My son is 24 and for two years now he gets violently sick to his stomach at least once a month which lasts about 24 hours. We thought he was having some alergic reaction to food but can't pinpoint it. He is very athletic and in great shape but gets these sessions for no apparent reasons. It seems like food poisoning but other family members are eating the same things. He has tried to vary his diet with no success. He is getting blood work tomorrow and an ultra sound of his pancreas at a doctors's advice but this seems like a mysterious allergy problem to us. Opinions?
