My husband has had a cough now for over 2 months (not productive) and it will not go away..when he talks, He coughs and even when He isn't, He coughs. He also is sick when He even thinks of food.He is very tired, cannot sleep. I have had Him to the Dr. She had alot of blood work done and a chest e-ray..it all looked good..there is something here that is not being caught . Would you please help me? Thanks! Betty Swartz
