Also called fever blisters, the small, fluid-filled lesions typically form near or on your lips and can cause symptoms such as tingling, itching, or burning.

For some, a lack of sleep, increased alcohol, another illness, stress, too much sunlight, irritation, or anything that can affect one’s immunity can spur an outbreak. That means that some patients can know not just when they feel an outbreak coming on but can know when they are more likely to have an outbreak due to their circumstances.
