I have certain allergy issue. My skin suddenly start swelling like caused due to honeybee stung. Some time it become severe (too much itching and rashes) but suddenly after 30 minute all become normal. Ithappensin 3 or 4 days. Only few times I have to take anti allergy tablet likecetrizine, otherwise it goes away itself. I think this is some kind of food allergy but Ihaven'table to find particular food responsible for it because I almost eat same things everyday. Roti dahi lassi sbji and all. Please suggest me the reason and cure.
