I had hfm a year and a half ago. I am a 35 yr old female. I had blisters on my mouth, face, and hands for a month. I tested negative for the herpes viruses. Fast forward to now. I will have a random cluster of blisters pop up on my lip or nose along with a few on hands randomly. I have tried Abreva and it makes them go away fairly quickly. My MD thinks I'm nuts. Lol. I think I'm carrying hfm. Is that possible? I've had it twice as an adult.
