Cold sores are from: infection. Cold sores are painful liquid filled blisters that can occur on the lips, roof of the mouth or the gums which are usually caused by the herpes simplex virus (HSV-1). Tingling &/or pain can herald the oncoming of cold sore 1 to 2 days prior to eruption. An estimated 80% of Americans have been exposed to Herpes Simplex Virus type 1. However, not all of those people will get cold sores.
