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.
Acyclovir ointment or cream works best if it is used at the first sign of cold sore symptoms. Side effects of the ointment may include mild pain or stinging at the site where it is applied. The U.S. Food and Drug Administration (FDA) approved acyclovir cream to treat recurrent cold sores in people older than age 12.
