Acupuncture is no better than placebo, usual care, or sham acupuncture for nonspecific acute pain or sub-chronic pain.[87] For those with chronic pain, it improves pain a little more than no treatment and about the same as medications, but it does not help with disability.[87] This pain benefit is only present right after treatment and not at follow-up.[87] Acupuncture may be a reasonable method to try for those with chronic pain that does not respond to other treatments like conservative care and medications.[1][88]

Like good footnotes, this sets PainScience.com apart from other health websites and blogs. Although footnotes are more useful, the update logs are important. They are “fine print,” but more meaningful than most of the comments that most Internet pages waste pixels on.
Blood tests are not routinely used to diagnose the cause of back pain; however in some cases they may be ordered to look for indications of inflammation, infection, and/or the presence of arthritis. Potential tests include complete blood count, erythrocyte sedimentation rate, and C-reactive protein. Blood tests may also detect HLA-B27, a genetic marker in the blood that is more common in people with ankylosing spondylitis or reactive arthritis (a form of arthritis that occurs following infection in another part of the body, usually the genitourinary tract).
There is controversy and scientific uncertainty about trigger points. It’s undeniable that mammals suffer from sensitive spots in our soft tissues … but their nature remains unclear, and the “tiny cramp” theory could be wrong. The tiny cramp theory is formally known as the “expanded integrated hypothesis,” and it has been prominently criticized by Quintner et al (and not many others). However, it’s the mostly widely accepted explanation for now. BACK TO TEXT
How to do it: Loop a resistance band around your ankles and lie on your right side, supporting your upper body with your right hand and forearm. Extend both legs out, feet flexed. Brace your abs in tight and lift your top leg up to hip height, rotating your leg to turn your toes down to the floor, keeping tension on the band. Lift your leg slightly higher than hip height, pushing against band, with heel rotated up to the ceiling. Return to hip height. Repeat 20 times quickly and then switch sides.
Exercise therapy is effective in decreasing pain and improving function for those with chronic low back pain.[50] It also appears to reduce recurrence rates for as long as six months after the completion of program[61] and improves long-term function.[57] There is no evidence that one particular type of exercise therapy is more effective than another.[62] The Alexander technique appears useful for chronic back pain,[63] and there is tentative evidence to support the use of yoga.[64] Transcutaneous electrical nerve stimulation (TENS) has not been found to be effective in chronic low back pain.[65] Evidence for the use of shoe insoles as a treatment is inconclusive.[51] Peripheral nerve stimulation, a minimally-invasive procedure, may be useful in cases of chronic low back pain that do not respond to other measures, although the evidence supporting it is not conclusive, and it is not effective for pain that radiates into the leg.[66] 
In most episodes of low back pain, a specific underlying cause is not identified or even looked for, with the pain believed to be due to mechanical problems such as muscle or joint strain.[1][4] If the pain does not go away with conservative treatment or if it is accompanied by "red flags" such as unexplained weight loss, fever, or significant problems with feeling or movement, further testing may be needed to look for a serious underlying problem.[5] In most cases, imaging tools such as X-ray computed tomography are not useful and carry their own risks.[9][10] Despite this, the use of imaging in low back pain has increased.[11] Some low back pain is caused by damaged intervertebral discs, and the straight leg raise test is useful to identify this cause.[5] In those with chronic pain, the pain processing system may malfunction, causing large amounts of pain in response to non-serious events.[12]

If low back pain gets worse or does not improve after two to three days of home treatment, contact a primary-care physician. The physician can evaluate the patient and perform a neurological exam in the office to determine which nerve root is being irritated, as well as rule out other serious medical conditions. If there are clear signs that the nerve root is being compressed, a physician can prescribe medications to relieve the pain, swelling and irritation; he or she also may recommend limitation of activities. If these treatment options do not provide relief within two weeks, it may be time to consider other diagnostic studies and possibly surgery.
