Large or small, more or less blisters appear on the lips, accompanied by pain, itching, and other discomforts, which may generally be related to the following reasons.

1. Virus Infection

Blistering on the lips is mostly caused by herpes simplex virus infection. After the initial infection, the virus lurks in the ganglia. When immunity declines, herpes is easy to relapse. In addition, blistering at the corners of the mouth may also occur during a herpes zoster attack on the head and face, but the rashes will be more numerous and wider.

2. Bacterial Infections

A herpes simplex attack can be accompanied by a secondary bacterial infection, which may also cause small pustules to appear in the corners of the mouth.

3. Hand, Foot And Mouth Disease

This is an infectious disease caused by an enterovirus and is common in children. Hand, foot, and mouth disease is mainly transmitted through the fecal-oral route or respiratory tract, and can also be transmitted through contact with blisters. The skin lesions can occur simultaneously on the hands, feet, mouth, or perioral area.

How To Relieve or Eliminate Lip Blisters

• Pay attention to rest, avoid fatigue and excessive pressure, and avoid excessive mental stress.
• Avoid using toothpaste, alcohol, and other irritating items to come into contact with the skin lesions.
• Avoid picking at the skin lesions to avoid ulceration or secondary infection.
• If it is a herpes simplex virus infection, you can wait for spontaneous recovery or use topical antiviral drugs such as acyclovir. The specific plan depends on the situation. If it is a bacterial infection or hand, foot, and mouth disease, it is recommended to seek medical treatment in time and treat it symptomatically under the guidance of a doctor. It is not advisable to use medication blindly.
• It is important to strengthen your physical fitness and exercise regularly to improve your immunity.

It should be noted that if the diagnosis cannot be confirmed, or the best treatment measures are not sure, or the symptoms are still not relieved after home treatment, please go to the hospital for further evaluation and treatment in time.
