Hi and thanks for your query, Being allergic or otherwise known as an atopic terrain requires careful considerations when dealing with disease, especially lung disease. This is because it might be difficult because, making a difference between purely allergy related symptoms and a comcomittant bacterial infection can be difficult. In your situation, doing a chest X ray can be very relevant. A complete blood count shall be very important in indicating either raised eosinophils, indicative of the allergic component, or raised white blood cells suggestive of a bacterial infection. Picking up an appointment with a pulmonologist could also be very helpful in redirecting and orienting your treatment plan. Thanks and hope this helps, Luchuo, MD.
