Is that small pimple on your lip herpes?

Not necessarily. Just because there's a small pimple on your lip, it doesn't necessarily mean it's herpes. There are various conditions that can cause small bumps or pimples on the lips, ranging from simple dry skin or skin irritation to more serious underlying health issues. Herpes labialis, or oral herpes, is one possible cause, but a proper diagnosis by a healthcare professional is essential to determine the precise nature of the pimple. Without consulting a medical provider, it's not advisable to assume or self-diagnose that a small pimple on the lip is definitely herpes.
