Symptoms of a cold sore may include:
Small, fluid-filled blisters on or around the lips or mouth
Pain, burning, or tingling sensation around the affected area
Itching or irritation
Swelling and redness around the affected area
Scabbing or crusting over the blister as it heals
Red flags that may indicate a more serious condition include:
Large, painful blisters
Blisters that spread to other parts of the face or body
Blisters that do not heal or continue to recur
Fever or other signs of infection
Treatment for cold sores typically involves antiviral medications to reduce the duration and severity of symptoms. These medications may be taken orally or applied topically.
Applying a cold, damp cloth to the affected area to reduce swelling and inflammation
Avoiding touching or picking at the blisters, which can spread the virus and delay healing
Using over-the-counter pain relievers such as acetaminophen or ibuprofen to alleviate pain and discomfort
Applying lip balms or creams to keep the affected area moisturized and prevent cracking or bleeding
Using sunscreen or lip balm with sun protection to prevent future outbreaks triggered by sun exposure
If symptoms persist or worsen despite treatment, or if cold sores occur frequently or in unusual locations, it is important to consult a healthcare provider for further evaluation and management.
