Some years i feel fine but all the sudden it rears it's ugly head and my main symptom always is the shortness of breath. i have been feeling ok and this morning i awoke sweating, sick in the stomach and short of breath. i don't believe the theory that stress and panic brings it on because i was a sleep and i don't find i am stressed...it just happens while sitting there. now, all day today, i feel short of breath, at rest, sitting here. Any ideas why MVP comes and goes. I had shortness of breath for a whole year a few years back! then all the sudden, i was fine. my doc does not have any answers. :rolleyes:
