<>Is “much” information really “just plain wrong”? I will establish this in the sections ahead with a steady supply of clearly explained references to the medical literature that patients can understand and professionals can respect. This extra layer of information in easy-to-use footnotes is available for any reader who wants to dig deeper and check my facts. For example, here’s a good start: In 2010, the Journal of Bone & Joint Surgery reported that “the quality and content of health information on the internet is highly variable for common sports medicine topics,” such as knee pain and low back pain — a bit of an understatement, really. Expert reviewers examined about 75 top-ranked commercial websites and another 30 academic sites. They gave each a quality score on a scale of 100. The average score? Barely over 50! For more detail, see Starman et al. BACK TO TEXT >
<>Nerve irritation: The nerves of the lumbar spine can be irritated by mechanical pressure (impingement) by bone or other tissues, or from disease, anywhere along their paths -- from their roots at the spinal cord to the skin surface. These conditions include lumbar disc disease (radiculopathy), bony encroachment, and inflammation of the nerves caused by a viral infection (shingles). See descriptions of these conditions below. >
<>The bony lumbar spine is designed so that vertebrae "stacked" together can provide a movable support structure while also protecting the spinal cord from injury. The spinal cord is composed of nervous tissue that extends down the spinal column from the brain. Each vertebra has a spinous process, a bony prominence behind the spinal cord, which shields the cord's nervous tissue from impact trauma. Vertebrae also have a strong bony "body" (vertebral body) in front of the spinal cord to provide a platform suitable for weight bearing of all tissues above the buttocks. The lumbar vertebrae stack immediately atop the sacrum bone that is situated in between the buttocks. On each side, the sacrum meets the iliac bone of the pelvis to form the sacroiliac joints of the buttocks. >
<>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 >
<>As with any sort of pain, it's crucial to figure out the source so you can properly treat it. Sharp or stabbing pain that extends beyond your low back or is accompanied by symptoms like abdominal pain, nausea, and vomiting, could be signs of various other conditions and definitely warrant a trip to the doctor. If you have a history of lower back injuries or disc problems, always see your doctor before trying any new exercise. >
<>White willow bark, for instance, may have pain-relieving properties similar to aspirin. Salicin, a compound found in white willow bark, is converted in the body to salicylic acid, just as aspirin is. Salicylic acid is believed to be the active compound that relieves pain and inflammation. Another herb sometimes used in the treatment of back pain is devil's claw. Devil's claw contains harpagosides, which are chemical compounds found to possess anti-inflammatory properties. >
<>Opioid analgesics: These drugs are considered an option for pain control in acute back pain. The use of these medications is associated with serious side effects, including dependence, sedation, decreased reaction time, nausea, and clouded judgment. One of the most troublesome side effects is constipation. This occurs in a large percentage of people taking this type of medication for more than a few days. A few studies support their short-term use for temporary pain relief. Their use, however, does not speed recovery. >
<>Research is being conducted on certain treatments that stimulate nerves to reduce chronic back pain. Your doctor may consider adding acupuncture to your treatment plan if you aren't finding relief with more conservative care. Another method your doctor might suggest is transcutaneous electrical nerve stimulation (TENS), during which mild electric pulses are delivered to the nerves to block incoming pain signals. >
