You need a proper ENT examination to ascertain the exact cause of your problem. Antibiotics will be of no use if your problem is due to allergy or due to a viral cause or due to acid reflux! As of now you are an unknown entity to me. Please use this Practo app on your smartphone, complete your profile there accurately and then get back to me by teleconsultation option or if you are located in Bangalore and around it, fix up an instant appointment to meet me directly. Either way, I will be able to advise you better and even prescribe the right medications to help you.
