What are coldsores?

Coldsore

A cold sore, also known as a fever blister, is a small, fluid-filled blister that develops on the lips or around the mouth. Coldsore are caused by the herpes simplex virus (HSV), which can be spread through close contact, such as kissing or sharing utensils.

Coldsore typically begin with a tingling or burning sensation on the skin. Within a few days, the blisters will appear and rupture, leaving a red, painful sore that may last for up to two weeks.

Although coldsore can be uncomfortable and unsightly, they are not usually a serious health concern. However, in some cases, they can lead to more severe complications, such as:

* Infection: Coldsore can become infected with bacteria, which can lead to redness, swelling, and pus formation.

* Scarring: Coldsore can leave behind scars, especially if they are severe or recurrent.

* Eye infections: Coldsore can spread to the eyes, causing conjunctivitis or corneal ulcers.

* Meningitis: In rare cases, HSV can cause meningitis, a serious infection of the brain and spinal cord.

There is no cure for coldsore, but there are a number of treatments that can help to relieve symptoms and speed healing. These treatments include:

* Over-the-counter medications: Over-the-counter pain relievers, such as ibuprofen or acetaminophen, can help to relieve pain and inflammation.

* Antiviral medications: Prescription antiviral medications, such as acyclovir or valacyclovir, can help to speed healing and reduce the risk of complications.

* Topical treatments: Topical creams or ointments, such as calamine lotion or zinc oxide, can help to soothe and protect the sores.

* Cold compresses: Cold compresses can help to reduce swelling and pain.

If you have a coldsore, it is important to see a doctor if the sores are severe, if they do not heal within two weeks, or if you have any symptoms of complications.
