Where Do Cold Sores or Fever Blisters Usually Develop?

Cold sores usually occur on the lips, gum, cheeks, chin and inside the nostril, according to Medical News Today. The skin around them mainly appears swollen and red. They can cause a burning sensation and then burst, leak a clear fluid and crust over after several days, explains WebMD.

The herpes simplex virus enters through the skin, causing cold sores. This condition is contagious and spreads from one person to another through kissing or touching an infected person’s saliva and sharing utensils. Symptoms include a sore throat, fever, pain around the mouth and swollen glands, notes WebMD. There is no cure for individuals infected with this virus, but patients should seek medical attention to reduce the duration and frequency of cold sores, reports Medical News Today.
