If you are among the 30-40% of people who suffer from cold sores or fever blisters you know there is nothing trivial about the condition. On average a patient will get a common cold sore 3 to 4 times a year. An active cold sore causes itching, pain and irritation, often causing the affected person to touch or scratch at the lesion. The cold sore virus is especially contagious because it weeps a fluid that is saturated with the virus. The virus can not only spread from person to person, but can also spread to different parts of the body. Be sure not to touch an active cold sore, and especially don’t touch another person or another part of your body after touching a cold sore. Herpes Keratitis is a cold sore virus that has been spread to the eyes, and is the leading cause of non-impact blindness in the United States. If you suffer from cold sore outbreaks there is help. While there is still no cure, there are some medications that can help. Be sure to bring it up to Dr. Glass or Cindie at your next appointment.
