Nose-located Cold Sore: Exploring Symptoms, Causes, Treatment Options, and Additional Information
Cold sores, a common affliction caused by the herpes simplex virus type 1 (HSV-1), can be a nuisance for many individuals. These unsightly blisters around the mouth are often triggered by a variety of factors, with sun exposure, stress, illness, and physiologic stress being the most common.
Sun exposure, or UV light, can provoke cold sore outbreaks by reactivating the dormant virus in nerves around the mouth. Stress, both physical (such as fatigue or other illnesses) and emotional, is another well-documented trigger. Illnesses like fever or infections may weaken the immune system, allowing the virus to reactivate. Other factors like physiologic stress (general bodily stress) can also prompt recurrences.
The early signs of a cold sore outbreak often include tingling or burning sensations on the lips, followed by blister formation. These blisters crust and heal over around 7 to 14 days.
Cold sores are distinct from canker sores, which are caused by injuries inside the mouth, stress, hormonal changes, or nutritional deficiencies. Canker sores develop inside the mouth, while cold sores tend to develop on the face.
HSV-1 can lead to complications such as encephalitis (inflammation of the brain) and keratitis (inflammation of the cornea in the eye), which tend to affect people with a severe infection and weakened immune system.
The main medications for cold sores are acyclovir, famciclovir, and valacyclovir, but they only help with symptoms and do not clear the underlying virus. Topical antiviral medications may ease symptoms and reduce healing times for cold sores, but a 2018 review found they have limited effectiveness.
Cold sores under the nose are generally not a cause for concern and will go away on their own. Prevention measures include avoiding kissing, sharing cups, cutlery, or straws, refraining from sharing lip balm or lipstick, avoiding touching a cold sore without washing the hands, and minimizing triggers such as stress or sun exposure.
Sources agree especially on sun exposure, stress, and illness as the most common and well-established triggers for HSV-1 cold sore reactivation.
