Low back pain may be classified based on the signs and symptoms. Diffuse pain that does not change in response to particular movements, and is localized to the lower back without radiating beyond the buttocks, is classified as nonspecific, the most common classification. Pain that radiates down the leg below the knee, is located on one side (in the case of disc herniation), or is on both sides (in spinal stenosis), and changes in severity in response to certain positions or maneuvers is radicular, making up 7% of cases. Pain that is accompanied by red flags such as trauma, fever, a history of cancer or significant muscle weakness may indicate a more serious underlying problem and is classified as needing urgent or specialized attention.
Exercise appears to be useful for preventing low back pain. Exercise is also probably effective in preventing recurrences in those with pain that has lasted more than six weeks. Medium-firm mattresses are more beneficial for chronic pain than firm mattresses. There is little to no evidence that back belts are any more helpful in preventing low back pain than education about proper lifting techniques. Shoe insoles do not help prevent low back pain.
Biofeedback is used to treat many acute pain problems, most notably back pain and headache. The therapy involves the attachment of electrodes to the skin and the use of an electromyography machine that allows people to become aware of and selfregulate their breathing, muscle tension, heart rate, and skin temperature. People regulate their response to pain by using relaxation techniques. Biofeedback is often used in combination with other treatment methods, generally without side effects. Evidence is lacking that biofeedback provides a clear benefit for low back pain.
MRI and x-ray for low back pain are surprisingly unreliable,1 because things like bulging discs usually aren’t a deal,2 most back pain goes away on its own,3 and trigger points (“muscle knots”) are common and can be alarmingly intense but aren’t dangerous.4 Most patients are much better off when they feel confident about these things. The power of justified, rational confidence is a huge factor in back pain.5 Sadly, many healthcare professionals continue to perpetuate the idea of fragile backs,6 which undermines that valuable confidence.
Herbal medicines, as a whole, are poorly supported by evidence. The herbal treatments Devil's claw and white willow may reduce the number of individuals reporting high levels of pain; however, for those taking pain relievers, this difference is not significant. Capsicum, in the form of either a gel or a plaster cast, has been found to reduce pain and increase function.
Hip flexors. These hardworking muscles are crucial in foundational movements such as sitting, standing, walking and running — they act as a bridge connecting your torso to your lower body. Some muscles in this group can be notoriously weak or tight and those of you who have ever had issues with this part of your body will know the uncomfortable pain of either all too well. There’s a lot of debate in the world of sports science over how much you should strengthen and stretch your hip flexors — we’ll explain.
Workers who experience acute low back pain as a result of a work injury may be asked by their employers to have x-rays. As in other cases, testing is not indicated unless red flags are present. An employer's concern about legal liability is not a medical indication and should not be used to justify medical testing when it is not indicated. There should be no legal reason for encouraging people to have tests which a health care provider determines are not indicated.
If low back pain occurs after a recent injury — such as a car accident, a fall or sports injury — call your primary-care physician immediately. If there are any neurological symptoms, seek medical care immediately. If there are no neurological problems (i.e. numbness, weakness, bowel and bladder dysfunction), the patient may benefit by beginning conservative treatment at home for two to three days. The patient may take anti-inflammatory medications such as aspirin or ibuprofen and restrict strenuous activities for a few days.
Low back pain (LBP) is a common disorder involving the muscles, nerves, and bones of the back. Pain can vary from a dull constant ache to a sudden sharp feeling. Low back pain may be classified by duration as acute (pain lasting less than 6 weeks), sub-chronic (6 to 12 weeks), or chronic (more than 12 weeks). The condition may be further classified by the underlying cause as either mechanical, non-mechanical, or referred pain. The symptoms of low back pain usually improve within a few weeks from the time they start, with 40–90% of people completely better by six weeks.
