Hydrogen peroxide works! Do this now: Sterilize a safety pin and poke a hole right in the middle of the sore, put hydrogen peroxide on lip multiple times (you will be able to feel it tingle in the sore), then the sore will dry out and you can squeeze the pus stuff out. When you see what comes out, you will know why it hurts so bad. You have to get that stuff out. Do this every day until you get it all out. It took me three days. It feels wonderful after having a swollen lip for a week. Relief!
