I'm a very allergic person. In July I started having typical hay fever symptoms. Running nose itchy eyes etc. took some antihistamines and sinus medication. No improvement. Was diagnosed with upper respiratory tract infection. Went on a course of antibiotics. Lost my voice but still no improvement. Started coughing. Was diagnosed with bronchitis in August. Another course of antibiotics, cough medicine and sinus meds. No improvement. In September went onto nebulizer with pulmicort. Still coughing so badly until I vomit. The coughing attacks occur day and night and are violent so much so that I gasp for breath. Went to a pulmonilogist. X Ray was clear but lung function test shows large airways functioning at 79%and small airways at 47%. Was given asthma pump, prednisone plus antihistamines. But I'm still coughing. What is wrong with me.
