Patient: Hi I’ve observed small blister near my lip,nearby skin is dry
Doctor: Hi.Thanks for your query.Noted your history of a common cold tablet. It seems you had flu.The blister as seen i n the picture is suggestive of a cold sore, herpes simplex.This is self-limiting without any definite treatment.Occurs when your body resistance is low. Take multivitamins. Take bed rest.I hope this answer helps you.
