One GP said I had asthma the next said COPD, I have never smoked but my mother did heavily. I can’t have a Pulmonary Function test due to a hernia. My current GP prescribed Spiriva Respimat but the side effects were intolerable..severe anxiety, constipation, fast heart beat but it did improve my breathing somewhat. What is others experience with this or similar medications? I am 74 years old.
