"Cold sores and fever blisters last seven to ten days. Most patients experience a fever or feeling of malaise and/or a tingling sensation before the actual manifestation. They are caused by a virus that many times remains dormant until a stressful situation or even a large dose of sunshine," says Dr. VijayaCherukuri from her Chino, California dental practice.
"In the past when a patient experienced a cold sore or fever blister there was little that could be done other than symptom relief, however, with the advent of laser treatment, we can many times eliminate the eruption or manifestation completely. Even if we are unable to catch it early, we can often reduce discomfort, duration and prevent a reoccurrence at the same site."
