Regardless of race, ethnicity, national orgin, gender, sexual orientation, religion, age, and ability, you will be treated and respected as a human being. Ignorance, bigotry, and harassment will not be tolerated. Thanks for your help. Thanks for your question. First, we need to carefully define our terms.
Cold sores are small red blisters that usually appear on the outside of the lip and mouth.
The virus can be transmitted from mouth to genitals quite easily. Canker sores can be quite painful, but they are not contagious. No one is quite sure why we develop canker sores. We are fairly sure they are not caused by a virus, but the rest remains a mystery. Distinguishing between herpes simplex I and other fever blisters is another matter.
