Cold sores are small, painful, fluid-filled blisters or sores that appear on the lips, mouth, or nose that are caused by a virus. These sores can be very painful and usually last several days to as long as a week. Unlike most viral infections, the cold sore virus is not always completely eliminated by the body’s normal defenses. For this reason, many cold sores often recur on a continuing basis and can be extremely difficult to treat.
Cold sores heal faster and cause less pain when they are treated topically with Pepto-Bismol or any type of antacid containing bismuth. To treat a cold sore is a very simple procedure. Once every four hours, use a cotton ball or swab to dab some liquid onto the cold sore. You can also purchase and use the OTC (Over-The-Counter) amino acid supplement lysine to treat a cold sore. The prescription ointment acyclovir known as Zovirax is another common form of treatment.
