Thanks for your question on Healthcare Magic. I can understand your concern. In my opinion, you should investigated thoroughly for allergic bronchitis. You might be allergic to some thing which is present in the environment. Points in favour of this are annual occurrence during the same period, skin lesions (rashes add hives), chest congestion, cough etc. So get done detailed allergy testing. Best treatment for allergic disease is identification of causative allergen and if possible complete avoidance of it. You should also take combination of antihistamine (levocetrizine or fexofenadine) and anti allergic (montelukast). Don t take prednisone as it is oral steroid and can harm you. So consult allergist and discuss all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
