Yesterday, My husband got so short of breath that we took him to the emergency room, they admitted him, They've taken to sets of x-rays, but, won't tell him much of what is going on, the doctor did say he'd be in the hospital for a while, and something about his COPD being asperated or something like that, does anyone know what that is? I'm really starting to worry , because no one is really telling us anything. Is it something we should be very concerned about?
