My lips are blue should i be worried?

Hard to say: Put you finger pad under your eye and pull down. If the soft inner lining of your lid is nice & pink, your lips are not blue from a bad heart, but may be cold or otherwise changed. If your inner lid is blue you have a problem.

Agree with Dr. F.: If you lips are blue only when it is cold, it is not a cause for concern. Have a healthy diet, exercise, drink plenty of water, have safe sex, and get HPV vaccine. Wish you good health! Nutrition: http://www.choosemyplate.gov/.
