Low Back Pain
Low back pain, also commonly referred to as lumbago, is a common disorder that involves bones and muscles of the back. About 40% of people have low back pain at some point of their lives. Also abbreviated as LBP, low back pain can be classified according to duration. Acute low back pain is pain that last for less than 6 weeks, sub-chronic back pain is pain lasting between 6 and 12 weeks and chronic back pain is pain lasting for over 12 weeks. Classification can also be done based on the cause of the condition and this can be – referred pain, mechanical or non-mechanical back pain.
Most low back pains are believed to be caused by mechanical issues such as joint or muscle strain and thus there is no identification or search for an underlying cause. If after conservative treatment, the pain does not fade away, or the pain is experienced along ‘red flags’ like fever, loss of weight and problems associated with movement and feeling, then further tests will be carried out to identify a serious underlying problem. Treatment is through conservative methods though some cases might require other advanced treatments depending on the situation.
Signs and Symptoms of Low Back Pain
In common low back pain, the pain will be experienced after movement that involves, twisting, bending forward, or lifting. The symptom can start after the movement or in some cases; they are experienced the following day in the morning. The pain described ranges from tenderness of some areas to diffuse pain. This pain might or might not worsen when the individual makes certain movements such as raising their legs, and certain sitting or standing positions. Sometimes the individual might experience sciatica, which is pain that radiates down their legs.
Most people experience their first acute low back pain when they are between the age of 20 and 40 years old. This is the first reason why most people see a medical professional in adulthood. In most case there are recurrent pain episodes and in more than 50% of the people, the following episodes are more painful than the first one. There are other problems that might emanate from low back pain. People suffering from chronic low back pain might experience sleep problems such as disturbances during sleep, less sleep satisfaction, short sleep durations and a great amount of time required to fall asleep. A large number of people suffering from chronic LBP will also show anxiety or depression symptoms.
Causes of Low back Pain

Most of the low back pains experienced by most patients will not have a clear underlying cause but are believed to result from non-serious skeletal or muscle problems such as strains or sprains. Some of the conditions that might contribute to low back pain include obesity, gained weight during pregnancy, poor posture, poor physical condition, poor sleeping position, stress and smoking.
