What Causes Cold Sores in the Nose?

Cold sores are caused by the herpes simplex virus type 1. Following the initial infection, the virus remains latent in the nerve cells of the human body. Some triggers can activate the virus, resulting in sores.

Common Triggers

Many factors that reactivate the herpes simplex virus are likely to lead to cold sores in the nose. By understanding these triggering factors, you can regulate and prevent outbreaks.

  • Stress: High stress levels tend to weaken the immune system, and this offers a ground for the virus to reactivate.
  • Illness: The development of cold sores occurs when a cold, the flu, or any other kind of infection weaken your immune system.
  • Sun Exposure: The sun’s ultraviolet (UV) rays can cause cold sores in some people. Even in winter in Canada, UV exposure can be significant, mainly when reflected in snow.
  • Hormonal Changes: The hormonal changes in women can contribute to facial outbreaks, particularly those that occur during menstruation.
  • Injury or Trauma: At times, facial or nasal injury can precipitate the outbreak.

  • Pain or itching inside the nose: The leading indicator is usually a tingle or itch.
  • Red, inflamed blisters: Such lesions can be painful and disturbing.
  • Swelling and tenderness around the nostrils: Swelling and sensitivity will appear around the area.
  • Crusty sores as the blisters heal: As the cold sores begin to dry and cure, they almost always result, for some time, in crusty sores, which can be pretty unattractive and annoying.

Over-the-Counter Remedies

  • Honey: Believed to have antiviral and antibiotic properties to help in an easy recovery.

Prescription Medications

  • Antiviral Pills: For those individuals who have terrible outbreaks or widespread outbreaks, an antiviral medication containing either valacyclovir or famciclovir can be obtained by prescription from a doctor. Both are easily obtainable in Canada by prescription from one’s doctor.
  • Preventive Therapy: For those individuals plagued by frequent outbreaks, a daily antiviral medication can be taken to reduce the number of outbreaks in the future. The Canadian healthcare systems support this, making preventive therapy options more available to the residents in Canada, which makes their task more straightforward to follow and reduces the frequency of the outbreaks of cold sores.

Tips for Prevention

Several lifestyle changes and precautions can reduce the possibility of such cold sore outbursts.

  • Relieve Stress: Exercise related to meditation, exercising, or deep breathing exercises.
  • Boost Your Immune System: Eat right, exercise often, and have enough sleep to make your immunity strong.
  • Protect Your Skin: Consider using a lip balm with SPF.
  • Avoid Close Contact: Refrain from kissing or sharing utensils with anyone with an active cold sore.

How to Hide Cold Sores

Though it is better to let cold sores heal on their own, knowing how to hide cold sores can make life a lot better. Sores that are visible around the nose can be covered up using a nonirritating concealer. One should also guard against scratching since doing so might cause scarring and delay healing.
