My husband has swelling of his feet, and a productive cough. He was recently treated (about 6 weeks ago) for pneumonia, which had been misdiagnosed for about 2 months. Sometimes, he feels like he has difficulty breathing, particularly at night or early morning. He has taken Lasix and this helps both his feet and his breathing. He had a triple bypass 4 years ago, and is a smoker. I feel like we are treating the symptom and not the cause. Ideas? Thanks!
