<>Regular updates are a key feature of PainScience.com tutorials. As new science and information becomes available, I upgrade them, and the most recent version is always automatically available to customers. Unlike regular books, and even e-books (which can be obsolete by the time they are published, and can go years between editions) this document is updated at least once every three months and often much more. I also log updates, making it easy for readers to see what’s changed. This tutorial has gotten 134 major and minor updates since I started logging carefully in late 2009 (plus countless minor tweaks and touch-ups). >
<>Bony encroachment: Any condition that results in movement or growth of the vertebrae of the lumbar spine can limit the space (encroachment) for the adjacent spinal cord and nerves. Causes of bony encroachment of the spinal nerves include foraminal narrowing (narrowing of the portal through which the spinal nerve passes from the spinal column, out of the spinal canal to the body, commonly as a result of arthritis), spondylolisthesis (slippage of one vertebra relative to another), and spinal stenosis (compression of the nerve roots or spinal cord by bony spurs or other soft tissues in the spinal canal). Spinal-nerve compression in these conditions can lead to sciatica pain that radiates down the lower extremities. Spinal stenosis can cause lower-extremity pains that worsen with walking and are relieved by resting (mimicking the pains of poor circulation). Treatment of these afflictions varies, depending on their severity, and ranges from rest and exercises to epidural cortisone injections and surgical decompression by removing the bone that is compressing the nervous tissue. >
<>I found the [Consumer Reports] articles on back pain very disappointing. I hope I can still trust Consumer Reports when shopping for a washing machine, but I have no confidence that I can trust them when looking for an effective medical treatment. They seem not to understand the difference between anecdotes and data, between a popularity contest and a controlled scientific study. These articles may do harm by encouraging readers to try treatments that don’t work and by suggesting that it is reasonable to prioritize testimonial evidence over scientific studies. On the other hand, these articles may do some good insofar as they may dissuade some patients from rushing to a doctor and demanding imaging studies or prescription drugs. >
<>A Cochrane review of 10 antidepressant and placebo trials showed no difference in pain relief or depression severity.62 The qualitative analyses found conflicting evidence on the effect of antidepressants on pain intensity in chronic low back pain and no clear evidence that antidepressants reduce depression in chronic low-back-pain patients. Two pooled analyses showed no difference in pain relief between different types of antidepressants and placebo. Another systemic review found different results: Antidepressants were more effective than placebo,9 but the effects were not consistent with all antidepressants. Tricyclic antidepressants were moderately more effective than placebo, but paroxetine and trazodone were not.9 Antidepressants were associated with significantly higher risk for adverse events compared with placebo, with drowsiness, dry mouth, dizziness, and constipation the most commonly reported.54 Duloxetine has recently been approved by the Food and Drug Administration for treatment of chronic low back pain and osteoarthritis,63 and evidence suggests effectiveness in chronic low back pain.58,57 >
<>Heat/ice therapy. Heat from a warm bath, hot water bottle, electric heating pad, or chemical or adhesive heat wraps can relax tense muscles and improve blood flow. Increased blood flow brings nutrients and oxygen that muscles need to heal and stay healthy. If the low back is painful due to inflammation, ice or cold packs can be used to reduce swelling. It’s important to protect the skin while applying heat and ice to prevent tissue damage. >
<>No, the lower back pain isn't in your head. But what is in your head could be making it worse. "Fear, anxiety, and catastrophizing can amplify pain," says Mackey. "People often get swept up in thoughts like This will never get better." Because brain circuits that process pain overlap dramatically with circuits involved with emotions, panic can translate into actual pain. Cognitive-behavioral therapy helps you recognize and reframe negative thoughts. Deep breathing can help, too, as can simply shining a light on dark thoughts. "Start by accepting that you have pain," Mackey says. "Then say to yourself, It will get better." >
<>Narcotic pain medications. Narcotic medications, also called opioids or painkillers, alter one’s perception of pain by weakening signals sent to the brain. Narcotic medications are most often used for treating intense, short-term pain, such as acute pain after an operation. Narcotics are rarely used to treat long-term pain, as they have many side effects and can easily become addictive. >
<>Spinal manipulation: Osteopathic or chiropractic manipulation appears to be beneficial in people during the first month of symptoms. Studies on this topic have produced conflicting results. The use of manipulation for people with chronic back pain has been studied as well, also with conflicting results. The effectiveness of this treatment remains unknown. Manipulation has not been found to benefit people with nerve root problems. >
<>After reviewing data regarding various treatments for lower back pain, the Agency for Health Care Research and Quality concluded that those suffering from back pain should first try conservative/natural treatments and then consider other options for lower back pain relief if pain persists. Oftentimes low back pain sufferers can find relief naturally by making changes to their lifestyles (including sleep, physical activity, stress and body weight) before choosing more intensive care options. >
<>A doctor may recommend a spinal injection to help reduce your back pain. There are different types of injections that doctors specializing in pain relief may use. For example, an injection of a corticosteroid can help relieve inflammation that is causing the pain. Depending on the kind of injection, your doctor may limit your number of doses per year to avoid possible side effects. >
