fever blister

Q. I believe the herpes virus that causes cold sores or fever blisters is similar to the virus causing shingles.

People who haven’t had fever blisters might not understand that urgency.

It appears as if a fever blister has taken over the monster’s entire head, rather than just the lips.

If you get fever blisters on your lips, they may be more likely to make an appearance this time of year.

And should they ask any questions about that, I intended telling them I had some fever blisters on my mouth, etc.
