have been wondering if the MVP contributes to symptoms of altitude
sickness. Four times in
my life I have been the only person to suffer altitude problems among a group of people who have traveled with me from sea level at the same time. Twice there was strenuous hiking involved, twice not. All 4 times included the nausea, severe headache, fatigue, clamminess, twice could not keep water down. Does this have to do with the heart not pumping enough blood per stroke, or what?
