What Could Cause my Lower Lip to Turn Purplish?
My lower lip started to turn bluish, worse at times, at the end of my pregnancy. After the birth of my baby, this did not resolve. It has worsened and now I can see that the superficial veins extending from my oral comissures down to the neck are more visible. I have a normal reading on pulse oximetry. What could be causing this? Should I be worried?
