HSV: Cold sores are. Caused by herpes simplex virus (hsv) and usually one catches it from kissing an infected person, eating utensils or touching that person's saliva. Usually form around mouth on lips and looks like small blisters. Currently laser treatment can cut the viruses cycle from 14 days to less than 5 or 6 days. Ask your dentist about the laser treatment, it has worked great on my patients.

Stress & virus: Cold sores are typically caused by a virus that lives in the nerves.Stress, or colds can cause cold sores to erupt because they both lower your immune system. The best way to treat them is to begin treatment as soon as you notice the "tingling" feeling before the break out. Daily lysine supplements may help. Daily anti-viral medicines will also help.

A viral infection.: Most cold sores are caused by the oral variety of the herpes virus. Once exposed to the virus, typically as a child, it never completely goes away. It flares up occasionally and causes sores which last from 7-10 days before healing. It tends to flare up when your immune system is down already, like after a cold, or lack of sleep, or times of stress. Topical antiviral creams can shorten the time.

TOT: Tincture of time! 7-10 days duration. Some anti- viral drugs can decrease symptoms and duration somewhat. Don't forget too much sun is a primary stressor that causes flare ups! alway protect lips when out for a day in the sun!

Herpes simplex: Once you get this virus it stays with you the rest of your life. Comes out when you have other infections, under stress, or for no good reason. If frequent you can reduce frequency and severity with antivirals. See a doctor.

Herpes simplex virus: Cold sores are painful blisters that can occur on the lips, roof of the mouth or the gums which are caused by the herpes simplex virus (hsv-1). Melissa officinalis or lemon balm (cream) expedites healing of cold sores. It can reduce healing time by half. Studies also show that regular use can help v recurrences. Brief supplementation with lysine 1, 000mg orally 3x / day at the onset, can work.
