Cold sores are caused by the herpes simplex virus 1 (HSV-1) and usually form around the mouth and on the lips. After appearing on the surface of the skin, the cold sore will blister and then begin to weep fluid about two days later. Once the weeping has ceased, a yellowish crust, or scab, will form over the sore. The scabbing process may itch and be uncomfortable, and though it should be left intact to protect the new skin growing beneath, there are measures you can take to ease discomfort and help healing.
Step 1
Refrain from picking at the scab. Allow the scab to flake off on its own, so the new skin beneath the scab has the opportunity to grow and heal over the sore.
Step 2
Apply either a warm compress or ice to the cold sore to ease pain. Wet a washcloth with warm water and place it against the cold sore, or hold an ice cube against the scab.
Step 3
Apply a small amount of topical lidocaine or benzyl alcohol cream, which are available over the counter, to keep the scab moist and ease discomfort. Apply cream twice per day, or according to the package recommendations.
Step 4
Use an over-the-counter pain medication, such as ibuprofen (Motrin) or acetaminophen (Tylenol), to treat pain caused by the cold sore. Ensure it is safe for you to take analgesics by asking your physician.
Tips and Warnings
- Cold sores are highly contagious, even during the scab stage. Refrain from mouth-to-mouth contact with another person, or sharing items that touch the mouth, such as towels or utensils, until the sore is completely healed. Always wash your hands thoroughly after handling your cold sore to prevent spreading the virus to other areas of your body, or other people. Anti-viral treatment is available for cold sores by prescription, but must be used before the blister stage of the cold sore begins. Contact your physician if you suspect a cold sore is forming to see if anti-viral medication is right for you.
