Uncertain: 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.

I have one bump on my upper lip! It has been there for 3 to 4 days! It came to a head and I popped it!! Now it is a flat hard spot! It does itch so I assumed it was a cold sore but it's not a blister or a cluster just one bump??
