Note to the writer : in text citation is a MUST AND REFRENCES CAN NOT BE OLDER THAN 5 YEARS.
Lower Back Pain
Low back pain in people may result from different problems in the numerous parts of the multifaceted, interconnected network of the spinal muscles, bones, nerves, tendons or discs in the lumbar spine (Manusov, 2012). Some of the typical sources include irritation of the large nerve roots found in the low back, which go to the legs. The smaller nerves supplying the low back may as well be irritated. Degeneration of the intervertebral disc and damage on the ligaments, bones, or joints are among the leading causes (Franks & Howley, 2011). At times, it becomes severe as one feels numbness, tingling, or weakness in the legs.
Acute care for a patient diagnosed with low back pain without any particular injury will involve the use of spinal manipulation, which may offer significant medical outcomes after approximately 3 to 6 months (Borenstein & Callin, 2012). In minimizing the reoccurrence of the condition, one requires understanding the disorder and its causes. Below are a number of recommendations for management and treatment of the low back pain.
Teaching points

Reassurance: patients have to be given an assurance that the pain may fade or heal by itself after some time. They are to involve themselves in a moderate exercise rather than a complete bed rest.
Cold and hot therapy: Effective pain relief may be achieved by alternating the cold and hot compress on the affected sites for about 15 to 20 minutes.
Tight fitted clothing should be avoided: It interferes with the flexibility when it comes bending, walking, or sitting, which all may aggravate the pain.
Chilling it: Ice is best used before 48 hours elapse after the injury (Borenstein & Callin, 2012). It helps to reduce the inflammation by covering up the pain and assists in the relaxation of the muscles.
Keep moving: One should keep going on with the daily activities since the spine forms the rest of the body. It thus requires taking part in the regular aerobic exercises including walking, swimming, as well as riding, but one should not overdo these activities (Franks & Howley, 2011).
Watch your posture and weight: Slumping often makes it hard for the back to support the weight. It is essential to look keenly at the posture while lifting heavy objects (Franks & Howley, 2011). Bending should not be done at the waist, however; one has to bend and straighten his or her knees. People must also eat appropriate diet and do exercise to maintain their weights within a healthy range for their heights. Overweight usually exerts excess pressure on the spine. One should also avoid standing for longer periods.
Avoid the smoking habit if its necessary: Routines such as smoking may increase one’s risks for the spine’s osteoporosis and other bone related problems. Osteoporosis often leads to compression fracturing of the spine; hence, the smokers have higher chances of developing low back pain as compared to nonsmokers (Borenstein & Callin, 2012).
Use an over-the-counter reliever: Some of the anti-inflammatory drugs including ibuprofen, aspirin, and naproxen sodium are always useful in relieving acute back pain (Manusov, 2012). However, it is significant that one consults with a doctor before taking the drugs for an explanation on the interactions they may have with other treatments .
Referral: In case the pain persists, then more advanced diagnostic or surgical interventions may be sought (Manusov, 2012). A transfer to a spine expert may be necessary when it interferes with the patient’s daily function.
Wear low heels: Individuals are to exchange their 4-inch pumps with low heels or flats especially less than one-inch (Franks & Howley, 2011). The high heels have the tendency of creating a more unstable stance and increases pressure on the lower spine.
