Posssibly anxiety: You should get tested 4 allergies. Is it only certain foods? This is important for your md to know. If it is more general, or random, it may be anxiety. You r probably now anxious about it & anxiety feeds itself & makes itself worse. Once physical causes r ruled out, find a therapist specializing in anxiety, esp. Exposure based treatment. Ativan, xanax (alprazolam) etc are addictive and not best treatment.
