What Are Lip Blisters?
Fluid-filled, inflamed bumps that form on the lips are known as lip blisters. Frequently referred to as fever blisters, lip blisters present with exposure to the infectious type 1 herpes simplex virus. Once exposed, the virus lies dormant in an individual’s system and may re-manifest at any time. The contagious virus may be passed through close, interpersonal contact, such as sharing drinking glasses or eating utensils and kissing. Treatment for lip blisters generally involves the administration of topical and, sometimes, oral medications to alleviate symptoms and discomfort.
