When you were sick, did you test for covid? Did you recently get a covid vaccine?
We've had reports from people that having covid and/or getting the vax can trigger herpes sores, and it can be really hard to get them under control.
Are you taking the Valtrex daily, as suppression? That would be my suggestion after you see the doc and get it confirmed that these are indeed hsv1 outbreaks.
You might be having an allergic reaction to something, which can look similar, or an allergic reaction to something you are using on your mouth might be triggering the outbreaks.
See the doc. Ask for them to do a PCR culture on a sore. Don't take any Valtrex until you see the doc. If you get a sore, don't do anything to it until the doc sees it. Let the doc see how it looks as is.
Good luck!
