Difference between a cold sore and a pimple on corner of mouth?

A doctor has provided 1 answer

Virus vs bacteria: A cold sore is a virus typically on lips or inside your mouth. A pimple is a bacterial infection. If it is truly a pimple it is bacterial and either infection in the gland in the corner of your mouth or on the skin near the corner. A cold sore is a herpetic virus, usually more painful typically lasting 10 days to 2 weeks.
