You can get blisters by accidentally biting your lips, burning your lips with a hot surface or food, brushing your teeth too vigorously, or getting infected by a virus from someone else. The most common cause of blisters on lips are cold sores, also known as fever blisters.

How to use: Apply a cream, ointment, or lip balm containing lemon balm to the affected area several times per day. You may also put diluted essential oil on a cotton ball and hold it on the sores for a few minutes. Continue using lemon balm for a few days after your sores have healed.

Cold sores — also called fever blisters — are a common viral infection. They are tiny, fluid-filled blisters on and around your lips. These blisters are often grouped together in patches. After the blisters break, a scab forms that can last several days.

You may be feeling afraid of talking to your partner about having a cold sore, or even dating someone with a cold sore. However, dating with cold sores is possible, if you’re open and honest about it.

Millions of people have herpes, and plenty of them are in relationships. For most couples, herpes isn’t a huge deal. Try to go into the conversation with a calm, positive attitude. Having herpes is simply a health issue — it doesn’t say anything about you as a person.

You Can Sue Someone Who Gave You HSV-1 or HSV-2. Herpes is an incurable sexually transmitted disease (STD). It requires a lifetime of prescription treatment and is characterized by large sores on the skin that are painful and tender to the touch.

Proof is hard to come by for HPV infection because though some strains can cause cancer and warts, more often there are no symptoms. The virus is typically cleared by the body without the infected person knowing he or she ever had it.

After someone is initially infected, the virus can lie dormant without causing any symptoms. But it can reactivate later, typically after some sort of stress like a cold, an infection, hormonal changes, or menstrual periods. Cold sores from HSV1 usually go away on their own within 5 to 7 days.

Herpes simplex, or cold sores Oral herpes usually appears as red sores in the mouth. When they appear outside the lips, they may look like blisters. Nicknamed “fever blisters,” these red, raised bumps can be painful. They’re also known as cold sores.

HSV-1 can cause “genital herpes,” but most cases of genital herpes are caused by HSV-2. Typically, someone with HSV-2 will have sores around the genitals or rectum. Symptoms are usually the most intense during the first outbreak and become less intense over time.

Cold sores are typically contagious for up to 15 days. You need to wait until all your cold sore symptoms have cleared – including the blister and any scabbing – to reach the point when cold sores are not contagious anymore.

The last stage in cold sore healing is when the scab and flakiness completely disappear, leaving healthy skin underneath (there is usually no scar left behind). Until that point, cold sores are not completely healed – which means, no kissing to avoid spread. This healing process can take 7-10 days.

Chapped lips will feel dry and tender but across the entirety of the lips, and generally, no blisters will form.

A mucous cyst, also known as a mucocele, is a fluid-filled swelling that occurs on the lip or the mouth. The cyst develops when the mouth’s salivary glands become plugged with mucus. Most cysts are on the lower lip, but they can occur anywhere inside your mouth. They’re usually temporary and painless.

BUMPS TO EXPECT WITHIN YOUR MOUTH There are tiny bumps on the inside corners of your mouth that are normal. As are the tiny bumps that often appear on the outside of your lips. These are not harmful, and are normal for nearly everyone.

Painless, and harmless, but can be bothersome because you are so aware of the bumps in your mouth. Mucoceles may also interfere with eating or speaking. Moreover, if left untreated, they can organize and form a permanent bump on the inner surface of the lip.
