What is lower back sciatica? What is lower back sciatica? The word sciatica portrays the indications of leg pain and possibly itchy, numbness or weakness that travels from the low back through the buttock and along the large sciatic nerve in the back of the leg. The medical diagnosis of sciatica is referred to as a "radiculopathy", which means simply that a disc has obtruded from its natural location in the vertebral column and is laying pressure on the radicular nerve in the lower back, which creates part of the sciatic nerve. The sciatic nerve is formed by the nerve roots coming out of the spinal cord into the lower back.

The sciatic nerve is the largest nerve in the human body, nearly the diameter of a finger. An significant matter to understand is that sciatica is a symptom of a problem -- of something squeezing or irritating the nerve roots that comprises the sciatic nerve. Sciatica occurs most often in people amid 30 and 50 years of age. It tends to grow as a outcome of general deterioration on the structures of the lower spine.

Most sciatica pain syndromes result from swelling and will get improved within two weeks to a few months. Also, since the spinal cord is not present in the lower (lumbar) spine, a herniated disc in this region of the anatomy does not present a chance of paralysis.

# Progressive weakness in the leg
# Bladder/bowel incontinence or dysfunction

Often there is not a specific traumatic outcome or activity associated with the onset of sciatica. Standing, sitting, heavy lifting, sneezing, or having a bowel movement may aggravate the pain. Lying down is generally the most comfortable position. Intermittently parenthesis, weakness and diminished bowel or bladder function will accompany sciatica, but these are uncommon symptoms. Sciatica causes pain, burning feeling, lack of sensation, or stinging radiating from the lower back and upper buttock along the back of the thigh to the back of the leg. Severe sciatica can make walking hard if not unbearable. Sometimes the indications of sciatica are worsened by walking or bending at the waist and relieved by lying down.

True sciatica arises when the sciatic nerve is pinched or irritated and the pain down the sciatic nerve is caused by this nerve (radicular pain) and is called a radiculopathy. When the pain is referred to the leg from a joint problem (called referred pain), using the word sciatica is not scientifically right. Nerve root tension tests can be used to confirm the occurrence of sciatica by attempting to reproduce the discomfort with certain motions and body positions. These tests are performed by a doctor and include moving the legs in certain ways that slightly stretch the sciatic nerve. Physical therapy and a home program of extending and strengthening exercises are very useful in letting a patient to return to full activity.

The lifetime prevalence of low back pain is 50-70%, and 5-10% of patients with low back pain have sciatica. For the first few days it is vitally significant to stay off your feet as much as possible. The worst thing you can do is get up and down again and again as this causes the nerve to become more irritated. Although soaking in warm baths relieve and lessen the pain, do not use heating pads at first while the nerve is inflamed. Stretched heat draws the tenderness in, keeping the swelling high. Most doctors tell their patients to apply ice packs directly on the lower back region for about twenty minutes at a time, each couple of hours. Although this can sense like torment, the cold pack helps lessen swelling. Mineral ice is also great at calming the pain and offering short-term relief. There are some alternative treatments available that you might find beneficial. Acupressure and acupuncture, herbal therapies, homeopathy and biofeedback and guided imagery are just a few.
