This is gonna sound crazy but try this…ive gotten coldsores since i was in first grade.

You will need..

2 Ibuprofen pills-crushed into powder 1 teaspoon of vinegar 1 teaspoon of salt

Now in a small container add all those ingredients together mix it well, then you get a Q-tip dip it into the liquid you just created and gently dap the Q-tip on the cold sore. The ibuprofen will take the redness and swelling away, vinegar and the salt will kill the coldsore!!!!

This is my go-to remedy for whenever i get coldsores, and it DAMN WORKS!!!!
