How long is it supposed to it take for cold sore/blister to go away?
A doctor has provided 1 answer
Generally 10-14 days: Without medication each sore takes 10-14 days to go away. However, you can have multiple sores that come up before one resolves and some people always have an active sore soemwhere. Your dentist or md can prescribe meds to help prevent outbreaks.
