If the size increases over a few days, multiple lumps appear, or pain becomes severe, please do not squeeze them yourself. A direct examination is needed to determine if prompt inflammation control is required.

For herbal medicine treatment, the prescription direction is determined by looking at these recurring conditions, as well as facial heat, sebum, and recovery speed.
