I bite it until it starts to bleed..a lot. One time I couldn't stop the bleeding for 15 minutes. Its so strange but I like to squeeze the blood out of my cut and just watch it flow out. I also kinda enjoy the way it tastes. I am so... show more I often bite my inner bottom lip and chew on it till I tear a huge hole in it.
Cold sores and fever blisters are painful, fluid-filled blisters on or near the lips caused by a virus called herpes simplex type 1. Cold sores are contagious and spread by touch. An over-the-counter medicine called docosanol (brand name AbrevaÂ®) may help cold sores heal faster and reduce symptoms.
How Long Do Cold Sores Last With Treatment? If your cold sore has lasted longer than two weeks, or the sore is too painful or unsightly to endure, go to the doctor. Your doctor can prescribe treatment to heal your cold sore in five to seven days, like Denavir and Xovirax. Abreva, an over-the-counter cold sore remedy available from the pharmacist's counter at most drugstores, is a topical cold sore medication that is FDA-approved to shorten the healing time of your cold sores.
