My cold sores got worse. they appear every month in small amounts either in my nostrils or lip. what should i do? i apply acyclovir

See a Derm: There is actually a very effective oral medicine that you can take. The dosage varies based on the number of outbreaks, either just when you feel one coming on or daily suppression. This would be something you could discuss.

See a dermatologist: You will get nowhere using a worthless product. They should be ashamed of selling this. ORAL acyclovir [valacyclovir is better] is effective if used correctly. It is completely safe, even if pregnant. First see a dermatologist to confirm the diagnosis.
