What if a cold sore wont leave?

Possible reasons why a cold sore won't leave:

- The cold sore is infected. If the cold sore is infected, it may take longer to heal and may require treatment with antiviral medication.

- The cold sore is unusually large or severe. Some cold sores are simply more severe than others and may take longer to heal.

- You have an underlying health condition. Some underlying health conditions, such as a weakened immune system, can make it more difficult for cold sores to heal.

- You're not taking care of the cold sore properly. Cold sores need to be kept clean and dry to heal properly. Avoid touching or picking the cold sore, and apply a cold compress to help reduce swelling and pain.

Here are some tips for treating a cold sore that won't leave:

- See a doctor. If your cold sore is severe or doesn't improve after a week or two, see a doctor. They can prescribe antiviral medication or other treatments to help the cold sore heal.

- Keep the cold sore clean and dry. Wash the cold sore with soap and water twice a day, and pat it dry. Avoid touching or picking the cold sore, as this can spread the infection.

- Apply a cold compress. A cold compress can help to reduce swelling and pain. Apply the cold compress for 15-20 minutes at a time, several times a day.

- Take over-the-counter pain relievers. Over-the-counter pain relievers, such as ibuprofen or acetaminophen, can help to relieve the pain of a cold sore.

- Avoid triggers. Some things can trigger cold sores, such as stress, fatigue, and sun exposure. Avoid these triggers as much as possible to help prevent cold sores from recurring.

If your cold sore does not improve after several weeks of treatment, see your doctor.
