Low back pain is very common. It often goes away after several days or weeks, but it may last for months or years or periodically recur. The main goal in treating low back pain is to decrease pain and allow people to resume their normal activities. Usual treatments for low back pain include drugs (painkillers, anti-inflammatory drugs, and muscle relaxants), physical therapy, back exercises, and education about ways to prevent back injury and deal with back pain. Some people use alternative treatments for low back pain, such as chiropractic or massage therapy.
