I've had cold sores before, obvs. My experience with them has led me to realize that none of the OTC stuff helps. Usually it just makes my lip bleed. Ew. Resigned to the fact that there's not much to do but tough it out, I thought I'd use the Google just in case I was missing some killer at home cold sore remedy.
No such luck.
I did find out that avoiding certain triggers of cold sores will lessen the frequency you get them. Here's the list:
- Infection, colds and flu
- Ultraviolet radiation, such as a sunburn
- Changes in the immune system
- Food allergies
- Dental work
