Cold sores, caused by the herpes simplex virus (HSV-1), remain dormant in the body and can reactivate due to stress, illness, or sun exposure. They usually appear around the lips, nose, or chin.
Initial symptoms include tingling, itching, or burning before visible blisters form. These blisters burst, ooze fluid, scab, and heal within 2-4 weeks. While cold sores often resolve naturally, antiviral medications like acyclovir can reduce healing time. Over-the-counter treatments like docosanol or lidocaine may numb the area, and natural remedies like aloe vera can soothe irritation.
Prevent outbreaks by avoiding triggers, managing stress, and protecting from sun exposure. Strengthen the immune system through diet, hydration, and sleep.
Cold sores are contagious, spreading through direct contact or shared items. Practice good hygiene to prevent transmission. Though no cure exists, treatments can manage symptoms and reduce outbreaks.
