<>“The Pain Perplex,” a chapter in the book Complications, by Atul Gawande. Gawande’s entire book is worth reading, but his chapter on pain physiology is certainly the best summary of the subject I have ever read, and a terrific reminder that good writing for a general audience can be just as illuminating for professionals. Anyone struggling with a pain problem should buy the book for this chapter alone, though you are likely to enjoy the whole thing. Much of the chapter focuses on one of the most interesting stories of low back pain I’ve read, and it is a responsible and rational account — although Gawande, like most doctors, seems to be unaware of the clinical significance, or even existence, of myofascial trigger points. >
<>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. >
<>Stretch. Don't sit slumped in your desk chair all day. Get up every 20 minutes or so and stretch the other way. "Because most of us spend a lot of time bending forward in our jobs, it's important to stand up and stretch backward throughout the day," Reicherter says. Don't forget to also stretch your legs. Some people find relief from their back pain by doing a regular stretching routine, like yoga. >
<>That’s a huge topic, but here’s one simple example of an extremely common problem with back pain science: control groups that don’t control. Rather than comparing a treatment to a good, carefully selected placebo, most studies use a comparison to a treatment that is allegedly neutral, underwhelming, or placebo-ish. That makes the results hard to interpret: if each works about the same, it could mean that the treatments are equally effective … or equally ineffective! So much back pain science has this problem — or any one of a dozen other weak points — that you can effectively ignore at least 80% of all back pain research, because it’s so far from the last word on anything. Good science is essential to solving these problems, but really good studies are also difficult to design and rare. BACK TO TEXT >
<>Paget's disease of the bone is a condition of unknown cause in which the bone formation is out of synchrony with normal bone remodeling. This condition results in abnormally weakened bone and deformity and can cause localized bone pain, though it often causes no symptoms. Paget's disease is more common in people over the age of 50. Heredity (genetic background) and certain unusual virus infections have been suggested as causes. Thickening of involved bony areas of the lumbar spine can cause the radiating lower extremity pain of sciatica. >
<>Injections. If other measures don't relieve your pain, and if your pain radiates down your leg, your doctor may inject cortisone — an anti-inflammatory medication — or numbing medication into the space around your spinal cord (epidural space). A cortisone injection helps decrease inflammation around the nerve roots, but the pain relief usually lasts less than a few months. >
<>There are a number of medications that can relieve back pain. Over-the-counter pain relievers, muscle relaxants, topical pain relievers and narcotics are all extremely effective in increasing your comfort. In addition, cortisone injections can decrease inflammation around the nerve roots and low doses of antidepressants can relieve certain types of chronic back pain. >
<>Three systemic reviews3,6,13 analyzed spinal manipulation therapy (SMT) for low back pain, including (1) high-velocity, low-amplitude manipulation of the spinal joints slightly beyond their passive range of motion; (2) high-velocity, low-amplitude technique rotating the thigh and leg; (3) mobilization within passive range of motion; and (4) instrument-based manipulations. There is moderate evidence of short-term pain relief with acute low back pain treated with SMT.6 Chronic low back pain showed moderate improvement with SMT, which is as effective as NSAIDs and more effective than physical therapy in the long term.6 Patients with mixed acute and chronic low back pain had better pain outcomes in the short and long terms compared with McKenzie therapy, medical care, management by physical therapists, soft tissue treatment, and back school.6 SMT was more effective in reducing pain and improving daily activities when compared with sham therapy.3 Dagenais13 found SMT effective in pain reduction in the short-, intermediate-, and long-term management of acute low back pain. However, a Cochrane review in 2004 on SMT in acute and chronic low back pain concluded that there was no difference in pain reduction or ability to perform daily activities with SMT or standard treatments (medications, physical therapy, exercises, back school, or the care of a general practitioner).3 >
<>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. >
