🌿 Overview
Cold sores are tiny blisters that show up on the lips or around the mouth, often when you are run down, stressed, or have been in a lot of sun. They tend to come back now and then. They usually clear on their own. Keeping the area clean, cool, and moisturized, getting good rest, and protecting your lips from sun all help while they heal.
Common signs
- A tingling or itchy feeling before a blister appears
- Small fluid-filled blisters on or near the lips
- Blisters that ooze and form a crust
- Mild soreness for a few days
- Sometimes appears when stressed, sick, or sunburned
