Cold sores, also called fever blisters, are a common viral infection (HSV-1). Sores are tiny, fluid-filled blisters on & around the lips. The exterior mouth blisters are often grouped together in patches. After the blisters break, a crust forms over the sore site. Cold sores usually heal in 1-4 weeks.

Causes may include: 
Stress, hormonal changes, fatigue, exposure to sunlight & wind, viral infection/fever or changes in the immune system

FEVER BLISTERS

"My daughter had a pea sized fever blister that was split and cracked for over a week. We got some soothie ice from a relative and by the next day it was almost fully healed. Very tasty and my daughter loved it ... she said 'my sore is disappearing'! Works fast and tastes great!" - A. R.
