My son has a pimple on his lip?

Good morning, ma'am,

You mention that it has been a few days, has the size of the lesion increased or decreased? Has the appearance changed?

Thanks for the feedback!

Usually, a cold sore evolves more or less quickly and manifests itself as blisters of fluid. However, it is impossible to determine the exact cause of this blister, and the diagnosis is beyond what can be done on this platform. I urge you to consult a doctor, if only as a precaution, in order to get the right diagnosis and, if necessary, not to delay the right treatment.

Sorry I can't be more helpful to you at this time.

With pleasure, do not hesitate if there is anything!
