Dermatology

Cold sores, also known as fever blisters, are small fluid-filled blisters that develop on and around the lips initially as blisters that later develop into ulcers and crust over. They are caused by viral infections and typically occur in clusters, healing within two to three weeks without scarring the skin.

They are triggered by the herpes simplex virus (HSV), a widespread virus transmitted through direct skin-to-skin contact. Contracting the virus commonly occurs during childhood, often through kisses from family members with cold sores. These viruses are contagious even when sores are not visibly present.

While there is no cure for cold sores, outbreaks can be managed through treatments like antiviral pills or creams. These treatments help in healing and reducing the frequency, duration, and severity of the episodes."


Cold Sore Symptoms
Cold sores exhibit the following symptoms:

• Itching
• Tingling sensation at the outbreak area
• Presence of fluid-filled blisters
• Swelling and redness
• Formation of a scab

During the initial cold sore outbreak, symptoms may persist longer, and additional symptoms may include:

• Sore throat
• Headache
• Upset stomach
• Burning sensation inside the mouth
• Painful gums
• Fever
• Muscle aches

Subsequent cold sore recurrences typically occur in the same location with milder symptoms.

When to Consult Your Doctor?
While you can often manage symptoms independently, consider scheduling an appointment with your doctor if:

• Cold sores persist for over 10 days.
• You have concerns regarding the size or severity of a cold sore, especially if it is large or painful.
• You are pregnant.
• You have a compromised immune system due to an underlying condition or recent chemotherapy treatment.
• Your child exhibits swollen, painful gums, or mouth sores.

Consult your Expert Doctor today at Rojmed Polyclinic while cold sores typically resolve on their own, it's advisable to seek medical guidance if you have a weakened immune system, the blisters fail to heal within two weeks, or if you experience severe symptoms. Additionally, consult a doctor if you experience eye irritation or if the frequency of cold sore recurrences increases."
