Many people have to deal with these painful blisters, caused by a common virus and usually found on or around the mouth. Here are ways to fight them off:

Take action fast. Start treatment at the first sign of a cold sore, usually a tingling or tickling sensation and a small bump.

Try heat or ice. Warm or cold compresses can relieve pain and swelling and may keep a blister from forming. Over-the-counter painkillers or fever reducers also can help.

Keep them clean .... Gently wash infected areas with a clean washcloth and hot, soapy water twice a day and dry thoroughly (don't scrub, which may further irritate sores). Also wash your hands regularly throughout the day.

... and moist. Coat your lips regularly with a petroleum-based product such as Vaseline or apply a zinc-based ointment, both sold over the counter.

Limit sun exposure. Ultraviolet rays can aggravate sores and cause new breakouts. When outside, wear sunscreen and use a lip balm with an SPF of at least 15.

Avoid touching them. Cold sores are contagious and spread easily to other people or other parts of your body. In particular, don't rub your eyes right after touching a cold sore; the virus can cause eye infections.

Change toothbrushes. Throw away your toothbrush after an outbreak so you're less likely to re-infect yourself.

Take care of yourself. A healthy diet, plenty of water, stress reduction techniques and adequate sleep will strengthen your immune system against viral outbreaks.

See a doctor. Prescription ointments and anti-viral medications can relieve symptoms and possibly speed healing, especially if a cold sore is very large and painful or hasn't gone away in one to two weeks.
