I got a pollen and dust allergy before three months. I am using my allergy vaccine regularly but my doctor told me that it takes some time to overcome the symptoms of allergy. I was given medications to get relief from cough and phlegm. But still, I have a cough. After taking medicines, my phlegm seems to be stuck in my head. I have a nasal blockage with high panic pressure on my cheeks. forehead, teeth, and ears. My ears are blocked. I am not taking any medicines now and I am using Nebulizer with saline, Atm, and Clenil. But I do not have any relief. I am getting relief from cough only by taking lemon juice with water. What to do?
