For two days my daughter has blue lips. In ER they check all to eliminate lung and heart disease (blood check with heart markers; ECG, lung xray) and all results are ok. She also has some problems with some sort varicose veins on vagina - she is waiting for the surgery. She is taking babycontrol pills.
Doctors in ER said that they dont know the cause of the blueish lips, and they write down "OUTSIDE FACTOR".
What is that and what to do?
