How do you heal cold sores once they come out?

Here are some ways to manage and help speed up the healing of cold sores once they come out:

1. Over-the-Counter Treatment: Use antiviral creams or ointments containing acyclovir, penciclovir, or docosanol. Apply them directly to the cold sore as soon as you feel tingling or see the beginning of a sore.

2. Ice Compresses: Apply an ice cube wrapped in a cloth to the cold sore for about 10 minutes several times a day. This can help reduce pain and swelling.

3. Petroleum Jelly: Apply a thin layer of petroleum jelly to the cold sore to keep it moist and prevent it from drying out. Avoid picking or peeling the skin.

4. Pain Relievers: If you experience pain or discomfort, consider taking over-the-counter pain relievers such as ibuprofen or acetaminophen.

5. Avoid Irritants: Be gentle when washing your face or applying makeup. Try not to touch the cold sore with your hands, as this can spread the infection to other areas of your skin.

6. Protect from Sun: Apply sunscreen to your lips and face if you're going to be outdoors, as UV rays can worsen the cold sore.

7. Oral Antiviral Medications: For frequent or severe cold sores, your doctor may recommend oral antiviral medications like valacyclovir or acyclovir.

8. Stay Hydrated: Drink plenty of fluids to keep your skin and body hydrated, which can help the healing process.

9. Avoid Stress: Stress can trigger or worsen cold sores, so try to manage your stress levels through techniques such as relaxation exercises or meditation.

10. Don't Share Personal Items: Avoid sharing personal items like lip balms, towels, and utensils to prevent spreading the infection to others.

If your cold sores are severe, persistent, or accompanied by additional symptoms such as fever, swollen glands, or eye infections, it's essential to see a doctor for further evaluation and treatment.
