Cold Sores

Cold sores are small, fluid-filled blisters that develop on or around the lips. These are also called fever blisters. Often, these blisters appear in groups of patches. The blisters may break open after a few days leading to clear fluid leaking and resulting to a scab that would occur for a few days. Healing period usually takes a few days to two weeks. The most common complication arising from cold sores is dehydration because of refusal to intake food and other sources of nutrition.
