12 months ago i was up and out from 6am for a 10-15mile hike with my dog every morning then again in the evenings then i caught a cold and since then i can barely walk from room to room at home without getting out of breath. I have constant pains in my chest and back where my lungs are and have trouble sleeping, when i lie down i wheeze a lot and have to sit up several times to get my breath back and it makes me sweat a lot, does or has anyone else experience these sort of symtoms ??
