Acute Lower Back Pain Causes and Prevention

Acute lower back pain is one of the most commonly prevalent and commonly ignored daily life health problems in working adults. The increasing incidence of acute back pain in adults in India can be attributed in part to sedentary lifestyle and in part to long working hours in bad postures.

The 21st century brought with it a great change in the way we work. Work has become complicated, more mentally exerting, involving little or no physical exertion. Typically, back pain is classified into acute (<12 weeks) and chronic (>12 weeks) based on the duration of the pain. It is quite essential to differentiate acute and chronic back pain as their causes, treatments and response to treatment varies hugely.

Most cases of acute lower back pain are caused by muscle spasms, which by itself is not a serious problem. However, acute back pain may be an early sign to a range of less common but more serious disorders and those should be ruled out.

Muscle Sprains and Spasms:

Muscle sprains or spasms are the most common causes of acute back pain in adults. Usually caused either by prolonged inactivity in an abnormal posture like falling asleep in cars/buses in a sitting posture, or falling asleep on the couch or bean bags. Back pain may also start after sudden over activity with little previous exposure to exercise. The back pain associated with muscle spasms is usually dull in nature but can be very sharp when moved in certain directions and is never associated with leg pains.

People often believe that complete bed rest cures back ache; but on the contrary, resuming normal activity (excluding strenuous exercise) often improves acute back pain caused by muscle spasms. So, it is recommended that people get back to routine activities as soon as possible except in cases of heavy work.

Prevention is always better than cure. Muscles spasms are less likely to happen in people who exercise regularly.

Ergonomic planning of the work desk, to minimize work related muscle issues and posture management helps in reducing the risk of developing back pain.
