How can I tell if a bump on my lip is herpes?

A bump on your lip from herpes often comes with a warning sign—you might feel a tingling or burning sensation before the bump shows up. When it is herpes, small red or clear bumps group together.

These bumps then turn into fluid-filled blisters that can pop, leaving painful sores that eventually crust over as they heal. In contrast, other bumps like a mucocele or a fibroma usually do not come with pain or a tingling feeling and do not form clusters of blisters.

If you notice that your bump was preceded by unusual sensations, has grouped blisters, or is painful, these may be signs of herpes. Remember that herpes bumps are usually more than just a single bump; they tend to appear in groups and follow a pattern. Herpes is contagious and you should avoid oral contact or sharing beverages and utensils with others during a flare of sores.
