My fingernails just turned blue. This has never happened to me before.
I've been having shallow breathing for a few weeks. I've had some kind of unidedtified illness for almost two months now, and symptoms have appeared and disappeared in this time. I thought I was getting better, and then I started to have troubles breathing. Now my fingers are shaking, but they aren't blue anymore. When they were, the edges of my lips were too. I have an appointment with an internist for the whole illness in two weeks, but I'm pretty scared about this whole blue thing. What should I do?
