Hello! You are thinking about herpes simplex, a viral skin disease caused by human herpes simplex virus infection. This disease usually occurs on the face, especially on the lips, mouth and nose. The typical damage is a blister of millet to mung bean size clustered on the basis of erythema, which is thin-walled and has clear contents, and forms a superficial rotten surface or yellowish scab after bursting. Temporary pigmentation can be left after healing. Conscious symptoms are mild, with burning sensation and mild itching. Generally, there are no systemic symptoms, but it often happens after a fever disease such as a cold. The disease is self-limited and can heal itself after 1 ~ 2 weeks.

Guiding opinions:

Usually in the diet, avoid spicy stimulation, eat more fruits and vegetables, arrange rest time reasonably, and don't be too tired. Acyclovir ointment can be used externally.
