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.
Treatment: There is no cure for cold sores. However, some medications may relieve pain and soften HSV crusts on the skin. These remedies include: 1  Denavir (pencyclovir cream), a topical antiviral cream recently cleared for marketing by the FDA that may decrease the duration of lesion pain and accelerate healing.
