The Do's & Don'ts of Cold Sores

Cold sores are small sores on the face or mouth. They are caused by the herpes simplex virus-1 ("HSV-1"). Initially, they cause pain, burning or itching before they crust over. They are most often on the lips, chin and nostrils. They can also be on your gums or the roof of your mouth. Several actions can prevent and treat cold sores. Regardless of the solution you choose, contact your doctor if they do not clear up within 10 days.

Don't Scratch

• No matter how irritating a sore may be, or what stage it is in, do not scratch or pick at it. Scratching could cause the cold sores to develop infections. If a sore becomes infected, you may need to visit a doctor or a pharmacist to get antibiotics.

Don't Kiss People or Borrow Lipstick

• When you have a cold sore, make sure that you do not kiss people. Cold sores are contagious as long as you have them. They are particularly contagious when they are blisters. In addition, avoid touching a weeping blister, as you could spread the infection you have to other people. Avoid borrowing lipstick or letting someone borrow yours.

Recognize the Signs

• As soon as you notice the signs of a cold sore coming on, you should react immediately. Cold sore signs include tingling, itching and burning. Purchase cold sore medication from your local pharmacist right away. Several nonprescription cold sore medications are on the market. After you purchase the medicine, be sure to read application instructions and follow those instructions carefully.

Prevention

• Take steps to avoid getting cold sores. Cold sores can be brought on by individual triggers, such as stress. Do your best to get rid of those triggers. Wash your hands regularly with soap and water. It helps protect you against sores, the flu and infections. In addition, use sunblock regularly, preferably one with zinc oxide or titanium. Be sure to drink plenty of water every day and avoid activity that can dry your skin, such as extremely hot baths or showers.
