Patient: HiI am 27.From my school days I am allergic to dust and smoke.I am also allergic to medicines like O2, ornida etc.From childhood I havebeen suffering from running nose and blocked nose most often.I have to take otrivin for blocked nose.This winter along with running nose I also found little problem in breathing sometimes.my chest feels heavy sometimes.A local Doctor prescribed me maxiflow inhaler and MontekLC.I don’t think these medicines will cure me completely.Please suggest what should I do.
