Cold Sores or Fever Blisters
Cold sores are caused by a virus in the herpes family (herpes simplex type 1). It has been estimated that up to 70% of the population has experienced a cold sore by the age of 14. These sores occur commonly on the lips and around the mouth. Cold sores tend to be a recurrent problem in approximately 45% of the population. They are often stimulated by exposure to sunlight, illness, or stress (emotional upset). Because of their association with other illnesses, cold sores have come to be known as fever blisters. Common symptoms include onset of a dull throbbing pain in the lip prior to any change in appearance. This will progress to localized swelling, redness, and a painful, blistery bump over the course of several days. The blister will rupture, form a painful red ulcer, and eventually scab over and heal without scarring (over the course of 7-10 days). Treatment includes the use of an anti-viral cream and anti-viral pills (Acyclovir) in some cases. This medication has been shown to significantly shorten the course of this disease. Your doctor can provide you with these medications. If you are pregnant or nursing, you will not be able to use these medications. These medications are not approved for use in children.
