Cold sores are decidedly not fun.
While they're common and they often aren't a cause for concern, they don't really look or feel great. They can be itchy and painful, and at some point, fluid starts to ooze from them — overall, they just don't make for a great experience.
Feeling a strange tingle around your mouth? Maybe you're noticing a slightly inflamed or itchy patch? If you've had cold sores before, you know exactly what that tingle means. If not, it's possible that you might be experiencing your first cold sore outbreak.
