For past week have been eperiencing moderate/ severe itching that result in hives after scratching. Am not finding link to a food allergy.

Food allergies. Milk, eggs, wheat, soybeans, fish, crustacean shellfish, tree nuts ; peanuts cause 90 % of food allergic reactions. Up to 15 million americans suffer from food allergies ; need to avoid not only certain foods but any ingredient that contains proteins derived from them. In some cases, anaphylaxis can result.
