Pain in the back anywhere below the ribs and up to the hips is called low back pain. It is a condition that affects over 90% of the population at one time or the other. Next to common cold, it remains the most common reason why people seek medical help. Many people who experience low back pain do not meet up with a doctor since it usually resolves on its own. They may suffer from any dull aches to sharp pains or even numbness. The pain characteristically lingers on for a day or two before it gradually subsides. In many, the pains keep recurring in varying intensities. Studies have shown that back pain is the single most reason cited by employees for taking maximum number of 'sick leaves'. Stresses and strains of daily living and overuse and misuse of the muscles of the back are the commonest causes of backache. Why is back pain so common? The curvature of the normal spine is such that, the bony column is weakest at two points. The cervical spine (the nape of the neck) and the dorsal spine are the weakest points. The lower back bears at least one half of the body weight. Hence, these points bear the brunt of repeated stresses and strains. Every joint has an optimum position of function, departures from which increase the likelihood of strains and pains. Over time muscle strains lead to an overall imbalance in the muscle structure. There is constant strain on the muscles, bones, tendons, discs etc. The most common cause of back pain is poor posture. The real pain might be triggered by sudden lifting of weights, a sudden turn or a wrench, a fall on the back, sitting in a cramped position for a long time, horse-riding, riding a tractor etc. Occasionally, it won't be one event alone which triggers your backache. You may have been doing things improperly for a long time » standing, sitting or walking, until suddenly one simple movement might trigger your pains. These so-called last straws to the already overburdened back are some of the following: Trauma: acute or chronic » unusual lifting, sudden wrenches, fall etc. Psychic factors like depression ' can cause lowered (poor) muscle tone and cause backache Any acute illnesses » can cause poor muscle tone Fatigue Pregnancy Obesity » causes increased lordosis General poor health Localized, focal infections Faulty structure of feet. What makes backache worse is that once the pain starts, in order to avoid stressing the painful parts, we tend to perform actions ( walk, stand, lift etc.) with the use of other muscles which are not used to moving in that pattern. This further increases the stress on the muscles
