Cold Sores : What You Should Know

Overview
Cold sores are small blisters that usually form around the lips or mouth. They are caused by the herpes simplex virus (HSV-1) and tend to resolve on their own. While not considered dangerous, they can be uncomfortable or cause concern.

What Causes Cold Sores?

Cold sores are caused by HSV-1, a common virus that can remain dormant in the body and reactivate from time to time. Triggers may include:

  • Stress
  • Fatigue
  • Illness
  • Sun exposure
  • Hormonal changes

How Cold Sores Spread

HSV-1 can spread through:

  • Kissing or close personal contact
  • Sharing eating utensils, lip balm, or towels
  • Touching the affected area and then touching another surface or person

Common Symptoms

Cold sore symptoms can vary, but may include:

  • Tingling or itching sensation
  • Small fluid-filled blisters
  • Redness or swelling
  • Mild discomfort or sensitivity

Self-Care Tips

Cold sores often improve within 7 to 10 days. The following tips may help manage symptoms:

  • Apply a cool compress to reduce swelling
  • Avoid touching or picking at the sores
  • Keep the area clean and dry
  • Identify and avoid potential triggers where possible

When to Seek Medical Advice

It is best to speak with a healthcare professional if:

  • Sores occur frequently or are severe
  • Healing is slow or incomplete
  • You experience other symptoms such as fever or swollen glands
  • You are unsure if the symptoms are related to cold sores
