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.
If the sore has already erupted and is beginning to scab, use an over-the-counter medication like Abreva to help ease symptoms and reduce redness. Cold sores typically last 7 to 10 days, so it all depends on how early you catch and treat it, says Dr. Welsh. Cold sores are caused by the herpes simplex 1 virus and don't pop up unless something triggers them -- usually stress or overexposure to the sun.
