What are the symptoms & stages of healing?
Fever blisters usually pass through multiple stages as noted by Mayo Clinic:
Stage 1: Many people feel an itching, burning or tingling sensation around their lips for a day or so before small, hard, painful lesions appear, and blisters erupt.
Stage 2: Small fluid-filled blisters typically break out along the border where the outside edge of the lips meets the skin of the face. Cold sores can also occur around the nose or on the cheeks.
Stage 3: The small blisters may merge and then burst, leaving shallow open sores that will ooze fluid and then crust over. Cold sores usually crust within four days and heal completely within 8 to 10 days.
HSV-1 is what causes fever blisters, and unfortunately, once you have them, you’re likely to find cold sores on lips again. Recurrences typically appear at the same spot each time and tend to be less severe than the first outbreak. The symptoms of your first outbreak of fever blisters may also come with additional issues such as:
- Painful swelling
- Open sores in the mouth
- Sore throat
