<>Moderate-quality evidence shows that non-benzodiazepine muscle relaxants (e.g., cyclobenzaprine [Flexeril], tizanidine [Zanaflex], metaxalone [Skelaxin]) are beneficial in the treatment of acute low back pain. Most pain reduction from these medications occurs in the first seven to 14 days, but the benefit may continue for up to four weeks.19,20 However, nonbenzodiazepine muscle relaxants do not affect disability status.19,20 Very low-quality evidence shows that a short course (up to five days) of oral diazepam (Valium) may also be beneficial for pain relief.19 Because all muscle relaxants have adverse effects, such as drowsiness, dizziness, and nausea, they should be used cautiously. Diazepam and carisoprodol (Soma) use should be brief to decrease the risk of abuse and dependence. There is also moderate-quality evidence that muscle relaxants combined with NSAIDs may have additive benefit for reducing pain.19 >
<>Imaging is not warranted for most patients with acute low back pain. Without signs and symptoms indicating a serious underlying condition, imaging does not improve clinical outcomes in these patients.9–11 Even with a few weaker red flags, four to six weeks of treatment is appropriate before consideration of imaging studies.8–10 If a serious condition is suspected, magnetic resonance imaging (MRI) is usually most appropriate. Computed tomography is an alternative if MRI is contraindicated or unavailable.10 Clinical correlation of MRI or computed tomography findings is essential because the likelihood of false-positive results increases with age.12–14 Radiography may be helpful to screen for serious conditions, but usually has little diagnostic value because of its low sensitivity and specificity.10 >
<>Pain in the lower back or low back pain is a common concern, affecting up to 80% of Americans at some point in their lifetime. Many will have more than one episode. Low back pain is not a specific disease, rather it is a symptom that may occur from a variety of different processes. In up to 85% of people with low back pain, despite a thorough medical examination, no specific cause of the pain can be identified. >
<>MRI (or magnetic resonance imaging) scan is a radiology technique which uses magnetism, radio waves, and a computer to produce images of body structures. MRI scanning is painless and does not involve X-ray radiation. Patients with heart pacemakers, metal implants, or metal chips or clips in or around the eyes cannot be scanned with MRI because of the effect of the magnet. >
<>Acupuncture: Acupuncture may provide even more relief than painkillers, according to one 2013 review. In 11 studies of more than 1,100 people, this Chinese medicine staple improved symptoms of lower back pain better than simulated treatments and, yes, in some cases, NSAIDs. The needles appear to change the way your nerves react and may reduce inflammation around joints (which is only one of the therapy's benefits), says DeStefano. >
<>Endorphins are hormones made naturally in your body. What most people don't know is that they can be just as strong as any manufactured pain medication. When endorphins are released in your body, they help block pain signals from registering with your brain. Endorphins also help alleviate anxiety, stress, and depression, which are all associated with chronic back pain and often make the pain worse. >
<>Once in a great while some cranky reader (always a guy) writes to tell me, “I didn’t learn anything from your book.” I’m a little skeptical about that, and it’s always tempting to start quizzing! There’s a great deal of information here, including analyses of recent research. Sure, readers who have already done a lot of reading about back pain might already be familiar with a lot of it — but you will know that going in, of course, and you’ll find the nuggets of new information and perspective that any keen reader is always looking for.

<>Dr. Richard Deyo, one of the great myth busters of low back pain research, believes that “low back pain is second to upper respiratory problems as a symptom-related reason for visits to a physician” — only the common cold causes more complaints. Hart et al puts low back pain in fifth place (lower because Hart oddly excludes chronic low back pain). Chronic low back pain is usually the kind that this book will examine. Andersson writes: “Although the literature is filled with information about the prevalence and incidence of back pain in general, there is less information about chronic back pain … .” Indeed, it is almost impossible to measure how much chronic low back pain there is: for every time that acute low back pain is the main reason for a visit to a physician, how many times does a patient mention low back pain as a secondary problem? Or sees an alternative health care professional about it instead? (Answer: pretty danged often.) So it’s actually possible that low back pain is the single most common reason that people seek help.

<>When you have back pain, sleeping can be hard. It can be a vicious cycle because when you don't get enough sleep, your back pain may feel worse. A poor sleep position can also aggravate back pain. Try lying on your side. Place a pillow between your knees to keep your spine in a neutral position and relieve strain on your back. If you need to sleep on your back, slide a pillow under your knees. Be sure to sleep on a comfortably firm mattress. >
