The baby bit his lips and rubbed something bitter.

Patient's question:

No

Doctor's answer:

Your condition may be chronic cheilitis. The cause of chronic cheilitis is not very clear and may be related to cold, dry seasons, smoking, alcohol, excessively hot food, licking lips, biting lips, and other bad habits. Sometimes it may also be related to psychological factors. It can be treated by applying decoction of Sophora flavescens externally, which may have a certain effect.
