Pain is a very difficult thing to measure. There's no lab test that can put it into an absolute number like a white blood cell count. Yet with 50 million chronic pain sufferers in the United States alone, there's got to be a better way to measure pain than the visual analog scale (VAS). Using this scale, patients assign a number from zero to 10 to rate their pain (zero is no pain, 10 is the worst pain). This is so subjective, even the patients can't tell if a rating of three today is better or worse than yesterday's three. Efforts are being made by pain researchers to develop an interactive, intuitive computer program that will help quantify (put into numbers) variable describing and defining pain (e.g., location, intensity, duration). There is also a need for some kind of chronic pain assessment tool that can measure improvement in pain levels. Being able to measure improvement would help researchers identify which treatment approaches are working best. In this study, researchers from ...
<p><strong>What Are Canker Sores?</strong></p>
<p>Canker sores (also called aphthous ulcers) are small, shallow, painful, craterlike ulcers that appear on the moist tissues lining the inside of your mouth. They often occur two or three at a time, but it’s not unusual for 15 or more to appear at once. Unlike cold sores, canker sores are not contagious. They range from simple to complex, and occur predominantly in people between the ages of 10 and 40, especially women. Canker sores usually heal within two weeks, but they may recur. While they typically pose no serious health threat, severe canker sores can lead to malnutrition. Even simple severe canker sores can make eating and talking an unpleasant experience.</p>
<p><strong>Who Gets Canker Sores?</strong></p>
<p>People of all ages can get canker sores.</p>
Mouth sores usually go away in 10 to 14 days, even if you don't do anything. They sometimes last up to 6 weeks. The following steps can make you feel better:
Avoid hot beverages and foods, spicy and salty foods, and citrus.
Gargle with cool water or eat popsicles. This is helpful if you have a mouth burn.
Take pain relievers like acetaminophen.
For canker sores:
Rinse with salt water.
Apply a thin paste of baking soda and water.
Mix 1 part hydrogen peroxide with 1 part water and apply this mixture to the sores using a cotton swab.
For more severe cases, treatments include fluocinonide gel (Lidex), anti-inflammatory amlexanox paste (Aphthasol), or chlorhexidine gluconate (Peridex) mouthwash.
Nonprescription medications, such as Orabase, can protect a sore inside the lip and on the gums. Blistex or Campho-Phenique may provide some relief of canker sores and fever blister...
