A member asked:

Does a red patch on your lip mean it's a cold sore?

Dr. Heidi Fowler answered

Specializes in Psychiatry

Not necessarily.: Cold sores are painful liquid filled blisters that can occur on the lips, roof of the mouth or the gums which are caused by the herpes simplex virus (hsv-1). If you are uncertain about the lesion, your physician or a dermatologist could help to identify it.

Dr Pappas and another doctor agreed
