Common Backache
The precise cause is unknown in three quarters of cases. Often the pain is localised in the lower part of the back, although about 25% of people have pain going down the legs. 60% recover within two weeks.

Treatment
Simple treatment is usually enough, eg rest (on a firm surface) for as short a period as possible, painkillers, heat or cold packs. Manipulation by a trained person may help, but often only gives short-term relief. X-rays are unlikely to show any abnormality in the vast majority of people.
Prevention is better than cure! Correct body weight and fitness are important. Sports can strengthen the back (eg swimming - crawl and breaststroke). Special exercises may help (from books or physiotherapists). It may be necessary to change lifestyle.
Contact the doctor if pain is severe, there is numbness or weakness of the legs, pain is present for more than two weeks, there are problems with bladder control or other symptoms cause concern.
