Those pesky blisters around your mouth – you might call them cold sores or fever blisters – are a common annoyance. But fear not! This blog will shed light on these little nuisances, from what causes them to how to find relief.
What are Cold Sores (Fever Blisters)?
Both terms refer to the same condition: a viral infection caused by the herpes simplex virus (HSV), typically HSV-1. These clusters of tiny, fluid-filled blisters usually appear on the lips or around the mouth. The good news? Cold sores are rarely serious and typically heal within 2-3 weeks.
How Do I Get Them?
HSV-1 is highly contagious and can spread through close contact, like kissing or sharing utensils. You can even transmit the virus if you have no visible symptoms! Once infected, the virus lies dormant in your nerve cells and can reactivate under certain triggers, such as:
Stress
Sunburn
Fever or illness
Fatigue
Menstrual cycle
The Stages of a Cold Sore Outbreak
A cold sore outbreak follows a predictable pattern:
Tingling or burning: You might feel an itching or tingling sensation around your mouth a day or two before the blisters appear.
Blister formation: Small, red bumps erupt, filled with clear fluid.
Ulceration: The blisters burst and become open sores, which can be painful.
Crusting and healing: A crust forms over the sore, and it gradually heals over several days.
Finding Relief: Treatment Options
While there's no cure for HSV-1, several things can help manage outbreaks and soothe discomfort:
Over-the-counter creams: These creams can shorten healing time and ease pain. Apply them as soon as you feel tingling.
Pain relievers: OTC pain relievers like ibuprofen or acetaminophen can help manage discomfort. In addition, products like Helocaine® contain a local anesthetic that helps manage the discomfort associated with cold sores.
Cold compresses: Applying a cold compress to the affected area can reduce inflammation and provide temporary relief.
Lip balm: Keeping your lips moisturized with a mineral oils or petroleum jelly-based balm can prevent cracking and promote healing.
