Cold sores, also known as fever blisters, are a common and often recurring viral infection manifesting as small, painful blisters around the mouth caused by the herpes simplex virus (HSV). While there is no cure for HSV, natural remedies can provide relief and promote faster healing.
A cold sore is a small, fluid-filled blister or group of blisters that appear on the lips or around the mouth. These blisters often burst, resulting in a rough, crusty patch on the skin.
Typically, the first sign of a cold sore is a tingling or itching sensation in a specific area near the mouth. After the blister forms, other symptoms might include a fever, a sore throat, and swollen lymph nodes. Cold sores are triggered by two types of the herpes simplex virus: type 1 or 2.
