**Pharmacist Identifies Three Key Instances to Seek Medical Advice for Cold Sores**
Cold sores, or fever blisters, are a common viral infection that many people experience. These small, fluid-filled blisters typically appear on and around the lips, often in patches, and can be triggered by stress, sun exposure, or illness. While cold sores usually heal within two to three weeks without scarring, it is essential to know when to seek medical advice about them.
Leading pharmacist Phil Day, Superintendent Pharmacist at Pharmacy2U, has shared expert advice on cold sores. He emphasises that cold sores are common, affecting approximately 1 in 5 people in the UK. Despite being uncomfortable and unsightly, they tend to clear up on their own within 7-10 days. However, there are specific instances where medical advice should be sought.
According to Phil, individuals should seek medical advice if a cold sore persists for more than two weeks, if the outbreaks are particularly painful or frequent, or if they occur near the eyes or if the person has a weakened immune system.
Cold sores can be triggered by various factors such as stress, fatigue, hormonal changes, sun exposure, cold weather, or physical injury to the area. Effective treatments include antiviral creams like aciclovir, cold sore patches, pain-relieving gels, over-the-counter painkillers, and maintaining cleanliness and dryness in the affected area.
Pharmacist Nyrah, known as @healthwithnyrah on TikTok, with a large following, suggests using paracetamol for pain relief and applying aciclovir cream five times a day to the affected area. Preventative measures for cold sores include using SPF lip balms, overall health maintenance, trigger avoidance, frequent hand washing during outbreaks, and refraining from scratching the sores.
The NHS notes that cold sores typically start with a tingling or burning sensation followed by painful blisters within 48 hours, which then burst and crust over into a scab. Cold sores are contagious from the first indication until complete healing, and to prevent spread, it is advised to wash hands thoroughly, avoid kissing or oral sex, and take precautions during the healing process.
In summary, being aware of the instances to seek medical advice for cold sores and adopting effective treatment and preventative measures can help individuals manage and reduce the impact of these common viral infections. By understanding the causes, symptoms, treatments, and preventive strategies, individuals can better navigate and address cold sore outbreaks effectively.
