Some causes of lower back pain include pressure on nerve roots, injury, spinal stenosis, osteoarthritis and herniated discs. The pain may also be caused by other conditions, such as spinal tumors, ankylosing spondylitis and bacterial infection, states WebMD. In many cases, the pain is associated with spondylosis, which is the degeneration of the spine due to wear-and-tear.
There are some risk factors that may increase the chances of getting lower back pain, which include genetics, pregnancy, weight gain, age, occupational risk factors, fitness level and mental health factors, according to the National Institute of Neurological Disorders and Stroke.
A diagnosis is necessary to know the specific cause of the pain. The condition can be diagnosed through X-ray, discography, mylograms, blood tests, bone scans, ultrasound imaging and MRI scans. Imaging tests may not be necessary, but may be recommended to rule out some causes.
Treatment of the condition depends on the severity of the pain. Surgical procedures are only recommended when it is confirmed that the nerve damage is worse. A surgery is also necessary when there are structural changes, states the National Institute of Neurological Disorders and Stroke. In most cases, treatment methods that are typically used include physical therapy, cold or hot packs, strengthening exercises, medication, traction and nerve-block therapies.
