A fever blister typically lasts for 10-14 days. It might also form on the gums or tongue. In most cases, the blisters generally form as groups and trigger swollen, reddened and tender wounds. The blister might drain transparent fluid that scabs after a few days. At this span, a fever blister is considered contagious.

A flare-up can settle without treatment, but there are various ways to effectively alleviate the pain and allow it to recuperate.

What are the causes?

The herpes simplex virus is known to cause a fever blister. It can spread or infect other body parts including the genitals.

The symptoms are not always present immediately. In some cases, the virus remains in a dormant phase within the body and can recur at any time. Usually, an outbreak occurs if the individual is not fully healthy.
