Cold sores are small, painful blisters that usually appear around the lips or mouth. They are caused by the herpes simplex virus (HSV-1) and are highly contagious. Most cold sores heal on their own within 1 to 2 weeks.
Common Symptoms
– Tingling or itching before a sore appears
– Small fluid-filled blisters
– Pain or burning around the lips
– Blisters that crust over before healing
– Sometimes fever, sore throat, swollen glands, or headache
What Causes Cold Sores?
The herpes simplex virus remains in the body after the first infection and can become active again due to:
– Stress
– Fatigue
– Illness
– Sun exposure
– Hormonal changes
– Cold or windy weather
Treatment Options
Although there is no cure, symptoms can be managed by:
– Using antiviral creams or tablets early in the outbreak
– Applying cold sore patches
– Taking pain relievers if needed
– Applying ice packs to reduce discomfort
– Getting enough rest and staying hydrated
How to Prevent Spreading Cold Sores
– Wash your hands after touching the sore
– Do not share towels, cups, utensils, lip balm, or toothbrushes
– Avoid picking or touching the blisters
When to See a Doctor
Seek medical advice if:
– The sore doesn`t heal within two weeks
– You develop multiple or severe sores
– The sore spreads near your eyes
– There are signs of infection such as pus, increasing redness, or fever
– You have a weakened immune system or frequent outbreaks
