My grandson is 12 years old and has asthma. Last year he missed 30 days of school because of cough. He was only in school one week and began coughing Friday and is still coughing today and will miss school again tomorrow. Friday the doctor said that it was a virus and gave him an antibiotic, cough syrup and a steroid nose spray. Yesterday, his regular doctor said that he has an upper respiratory infection and gave him prednisone and lidocane for his throat. He says that he has a very sensitive nerve in his throat that triggers the cough. He says another child would probably not even have this cough. There have been many times that this doctor has said that he has a tic. He went all summer out of school and only had a cough onetime and it only lasted 3 days. His regular doctor did send him to a neurologist one time but, nothing ever came of it. We are at our wits end. Please help.
