An allergic reaction can be mild and self limiting and present as hives, rash, itching, sneezing, watery eyes, etc. More severe life threatening reactions can range from for example,swelling of the face, eyes, lips, tongue, difficulty breathing, wheezing, difficulty swallowing, etc. which require prompt medical interventions. Each exposure to the allergen typically makes the reaction worse. Over the counter medications or antihistamines which may be used for mild reactions are benadryl and loratadine. Prescription medications such as hydroxyzine, corticosteroids, etc. may be used in more difficult cases. I would strongly suggest that you have an evaluation by your primary care provider to ascertain what causative factor is responsible for your symptoms. Allergic reactions can again be very serious.
