i have noticed lately that my breathing is not normal, i dont feel like im getting enough air and i feel like i cant catch my breath sometimes. i have noticed twice that my lips turned blue for no particular reason, the second time being yesterday, i wasnt doing anything but riding in a car, i was putting vaseline on my lips and looked in the mirror and my lips were blue, my boyfriend looked at me at the same time and asked if i was ok, noticing i had blue lips, i felt ok just a bit lightheaded.? any ideas? thank you
