My husband has been coughing for 8 weeks. The doctor told him he had a lung infection and put him on antibiotics. The cough persisted. Because he is on blood pressure medication, he was switched to a different type. He is stil coughing, but less. Tonight he has the feeling of mucus in his throat which he can t swallow and is also unable to blow his nose. In addition, he has indicated over the past few months his eyes are always watering. He is a Type 2 diabetic and just recently began insulin injection, once a day. He also has 8 stents from heart attacks,. Is there anything to worry about? His lung X-ray came back fine and tomorrow he gets his results wrt a pulmonary exam. I thought it was a free service. Sorry!!
