<>Spinal disc degeneration coupled with disease in joints of the low back can lead to spinal-canal narrowing (spinal stenosis). These changes in the disc and the joints produce symptoms and can be seen on an X-ray. A person with spinal stenosis may have pain radiating down both lower extremities while standing for a long time or walking even short distances. >
<>Low back pain is the fifth most common reason for all physician visits in the United States.17,29 Approximately one quarter of US adults report having low back pain lasting at least 1 whole day in the past 3 months,17 and 7.6% report at least 1 episode of severe acute low back pain within a 1-year period.8 The prevalence rates of low back pain in athletes range from 1% to 40%.5 Back injuries in the young athlete are a common phenomenon, occurring in 10% to 15% of participants.18 It is not clear if athletes experience low back pain more often than the general population. Comparisons of wrestlers,27 gymnasts,60 and adolescent athletes40 have found back pain more common versus age-matched controls. Other comparisons of athletes and nonathletes have found lower rates of low back pain in athletes than nonathletes.67 >
<>Lumbar radiculopathy: Lumbar radiculopathy is nerve irritation that is caused by damage to the discs between the vertebrae. Damage to the disc occurs because of degeneration ("wear and tear") of the outer ring of the disc, traumatic injury, or both. As a result, the central softer portion of the disc can rupture (herniate) through the outer ring of the disc and abut the spinal cord or its nerves as they exit the bony spinal column. This rupture is what causes the commonly recognized "sciatica" pain of a herniated disc that shoots from the low back and buttock down the leg. Sciatica can be preceded by a history of localized low-back aching or it can follow a "popping" sensation and be accompanied by numbness and tingling. The pain commonly increases with movements at the waist and can increase with coughing or sneezing. In more severe instances, sciatica can be accompanied by incontinence of the bladder and/or bowels. The sciatica of lumbar radiculopathy typically affects only one side of the body, such as the left side or right side, and not both. Lumbar radiculopathy is suspected based on the above symptoms. Increased radiating pain when the lower extremity is lifted supports the diagnosis. Nerve testing (EMG/electromyogramspina bifida >
<>You know that calcium is key for strong bones, but Japanese researchers have identified something else you need: vitamin K. It’s believed that the vitamin, found in broccoli, spinach, and other dark leafy greens, helps calcium deposit in the bones, making them denser. The stronger your bones, the stronger your whole body—and the lower your chances of an injury that could cause back pain. >
<>Your doctor will first ask you many questions regarding the onset of the pain. (Were you lifting a heavy object and felt an immediate pain? Did the pain come on gradually?) He or she will want to know what makes the pain better or worse. The doctor will ask you questions referring to the red flag symptoms. He or she will ask if you have had the pain before. Your doctor will ask about recent illnesses and associated symptoms such as coughs, fevers, urinary difficulties, or stomach illnesses. In females, the doctor will want to know about vaginal bleeding, cramping, or discharge. Pain from the pelvis, in these cases, is frequently felt in the back. >
<>Transcutaneous electric nerve stimulation (TENS): TENS provides pulses of electrical stimulation through surface electrodes. For acute back pain, there is no proven benefit. Two small studies produced inconclusive results, with a trend toward improvement with TENS. In chronic back pain, there is conflicting evidence regarding its ability to help relieve pain. One study showed a slight advantage at one week for TENS but no difference at three months and beyond. Other studies showed no benefit for TENS at any time. There is no known benefit for sciatica. >
<>Exercise therapy appears to be slightly effective at decreasing pain and improving function in adults with chronic low back pain.30 In subacute low back pain, there is weak evidence that a graded activity program improves absenteeism.30 In acute low back pain, exercise therapy was no better than no treatment or conservative treatments. Exercise therapy using individualized regimens, supervision, stretching, and strengthening was associated with the best outcomes. The addition of exercise to other noninvasive therapies was associated with small improvements in pain and function. >
<>Grandma was right! Slouching is bad for you. And poor posture can make back pain worse, especially if you sit for long periods. Don't slump over your keyboard. Sit upright, with your shoulders relaxed and your body supported against the back of your chair. Try putting a pillow or a rolled towel between your lower back and your seat. Keep your feet flat on the floor. >
