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.
Dr. David Schleimer Dr. Schleimer. 4-5 days: Abreva is a medicament (not an anti-viral) which the fda has approved to be used in shortening the life of cold sores. Abreva: It is recommended that this be used for up to 10 days but not necessarily if the cold sore is healing.
