Also called fever blisters, you don’t get cold sores from fevers or colds but they can be triggered by them. The virus that causes cold sores is usually passed via a kiss, shared utensils, or other close contact. OTC creams and ointments may help discomfort and speed healing. Frequent sores may require a prescription. Cold sores are a top mouth problem. Other problems include canker sores, TMJ, bad breath, and mouth cancer.
This cold sore bothers me a lot. At first, I thought it was just an ordinary chapped lips, but when it didn't heal after three days of treating it with lip balm medications...I figured it is a cold sore. I hate it and the looked if it.
