Lastly, im not sure what caused it, but I had really chapped, swollen lips last week that resulted in tiny pin sized blisters along the whole rim of my top
lip and 1 small, but still larger,
blister on my lower
lip. It wasnt painful, just felt sunburned or chapped. I'm not sure if it's due to tanning too much, a reaction to my chapstick/ new toothpaste, or whether I got a cold sore from my ex (I never saw one on him).
