Sciatica is a form of radiculopathy caused by compression of the sciatic nerve, the large nerve that travels through the buttocks and extends down the back of the leg. This compression causes shock-like or burning low back pain combined with pain through the buttocks and down one leg, occasionally reaching the foot. In the most extreme cases, when the nerve is pinched between the disc and the adjacent bone, the symptoms may involve not only pain, but numbness and muscle weakness in the leg because of interrupted nerve signaling. The condition may also be caused by a tumor or cyst that presses on the sciatic nerve or its roots.
2016 — More editing, more! Added some better information about pain being a poor indicator, and the role of myofascial trigger points. This article has become extremely busy in the last couple months — about 4,000 readers per day, as described here — so I am really polishing it and making sure that it’s the best possible answer to people’s fears about back pain.
If the pain is still not managed adequately, short term use of opioids such as morphine may be useful. These medications carry a risk of addiction, may have negative interactions with other drugs, and have a greater risk of side effects, including dizziness, nausea, and constipation. The effect of long term use of opioids for lower back pain is unknown. Opioid treatment for chronic low back pain increases the risk for lifetime illicit drug use. Specialist groups advise against general long-term use of opioids for chronic low back pain. As of 2016, the CDC has released a guideline for prescribed opioid use in the management of chronic pain. It states that opioid use is not the preferred treatment when managing chronic pain due to the excessive risks involved. If prescribed, a person and their clinician should have a realistic plan to discontinue its use in the event that the risks outweigh the benefit.
The site navigation utilizes arrow, enter, escape, and space bar key commands. Left and right arrows move across top level links and expand / close menus in sub levels. Up and Down arrows will open main level menus and toggle through sub tier links. Enter and space open menus and escape closes them as well. Tab will move on to the next part of the site rather than go through menu items.
In the vast majority of patients with low back pain, symptoms can be attributed to nonspecific mechanical factors. However, in a much smaller percentage of patients, the cause of back pain may be something more serious, such as cancer, cauda equina syndrome, spinal infection, spinal compression fractures, spinal stress fractures, ankylosing spondylitis, or aneurysm.
Analgesic medications are those specifically designed to relieve pain. They include OTC acetaminophen and aspirin, as well as prescription opioids such as codeine, oxycodone, hydrocodone, and morphine. Opioids should be used only for a short period of time and under a physician’s supervision. People can develop a tolerance to opioids and require increasingly higher dosages to achieve the same effect. Opioids can also be addictive. Their side effects can include drowsiness, constipation, decreased reaction time, and impaired judgment. Some specialists are concerned that chronic use of opioids is detrimental to people with back pain because they can aggravate depression, leading to a worsening of the pain.
Acupuncture is moderately effective for chronic low back pain. It involves the insertion of thin needles into precise points throughout the body. Some practitioners believe this process helps clear away blockages in the body’s life force known as Qi (pronounced chee). Others who may not believe in the concept of Qi theorize that when the needles are inserted and then stimulated (by twisting or passing a low-voltage electrical current through them) naturally occurring painkilling chemicals such as endorphins, serotonin, and acetylcholine are released. Evidence of acupuncture’s benefit for acute low back pain is conflicting and clinical studies continue to investigate its benefits.
The hip flexors play an important role in everyday mobility and exercise. Involved in pulling the knee toward the hip, most movements either directly or indirectly use the hip flexors. That’s why even the slightest injury can cause great discomfort. Learn how you can recover from a hip flexor injury, and what precautions can be taken to avoid them.
