101.A Red-hot Cure. Have you ever had an operation？ If you have， you’ll know that surgical scars can leave you with a burning pain for months and sometimes even years. Frankly speaking， the pain is sometimes so unbearable it’s hard to even stand the weight of your own clothes on the scars. Generally speaking， most ordinary painkillers won’t work. Besides， they are so powerful that they may cause side effects. Fortunately， according to a recent study， doctors say there is a red-hot cure： chili peppers. An ointment is made from the ingredient that makes chili peppers hot. It kind of short-circuits the pain. The ointment is sold in a tube that lasts a month and costs only US$16. It’s considered the newest， most creative and inexpensive way of dealing with the problem.
