I have recently developed a small red rash with a few little bumps below my lip. Prior to the break out, my lips and chin itched or tingled for a week, and now that i've broken out, the rash, though tiny, itches like crazy. Also, I am sometimes experiencing itching and tingling around my lips and mouth even where no rash appears. Is this oral herpes, or is it dermatitis or eczema or something else? PLease help!
