I and 73 years old. I was diagnosed with COPD in the late 90's. I walk one lap around the track every morning, and walk at least 2,000 steps per day. I also use the Breather 4 times a day, take Trelegy once in the morning and have a rescue inhaler. I have shortness of breath when I go up hill or up stairs, when vacuuming the floor or washing the car etc. For the last couple of weeks I have had more mucus than normal, particularly if I recline in the recliner or lay on my back. I don't get it as much if I stand, or walk or sit upright. I live alone and do all my shopping and house cleaning. Could this be a COPD flare up? I don't
