yes I'm sure, I would get them on my lips then somehow they transfered there, I have been to the doctor for them and have had them looked at including in my nose. I only get them in the left nostril and like 2-3 at a time cause they just spread cause of the close courters. I have been given valtrax in the past but does not work at all so Now I have acyclovir but have not taken it more than once 1 pill. cause I didn't know if it would feed or help candida in anyway, wasn't sure? I get them when I get a cold, and now I have them ( i dont have a cold but my nose is so dry fromt the weather and sinus thing I have going on)
