I keep getting cold sores! how can i prevent this from happening?

Reduce stress: Cold sores are from a virus that is permanently in your "system" and comes out when you're stressed, lack of sleep, minor trauma, lowered resistance, etc. Once you've got one, you'll always have it. Often treated by a dentist using s soft tissue laser (without actually touching the sore) & makes them heal faster. See your md if medical issues exist.

Consult dr: Try to find out why your immune system is compromised. Sleep, rest, hormonal changes, nutrition, stress, all play a role, as do other medical problems. I suggest a goo medical work up.
