sometimes i have trouble breathing --feel tightness in my upper chest & throat-- i have allergies to juniper & ragweed that include itching & sometimes breathing---- this is different & i read symptoms of copd-- i do have a cough but not all the time-- it seems worse when I sit down. sometimes at the end of the day my legs feel swollen but don t look swollen. I asked my Dr. about a chest x-ray & or a breathing test & she didn t think it necessary-- Thank You for your thoughts on this, Cathy
