Cold sore, am i on the right track?

Hello, I've had a cold sore for 4 days. I never had one before, so the first day I scratched away not knowing that the hell it was!! Its on my lower lip, literally on it, not around it, its not that painful. By night time it was a big bump and I read online to use acetone. I did that. DID NOT work. I also put on toothpaste at overnight and it didn't do much. I used salt as well, it burned like hell and didn't do much. The second day I mostly just left it alone, I think I used salt sometimes but still nothing.I also iced it a couple of times. On the third day I bought abreva and it helped a bit, I am also using carmix al these days, today is the 4thday, it seems noticibly smaller, still using abreva and carmix and took 3 L lysine 500mg earlier. How much longer do you guys think until is gone? The swelling is gone, its mistly just sort of a little tender and it hurts a bit when I clean it of course its like a smal open wound. Am I using the right things? Thank you in advance !
