Your back is a complex structure made up of bones, muscles, nerves and joints and so pin-pointing the exact cause of the pain can often be difficult. However, most cases of lower back pain are not caused by serious damage or disease but by sprains, minor strains, minor injuries, or a pinched or irritated nerve.

     Back pain can be triggered by everyday activities at home and at work, or it can develop gradually over time as a result of sitting, standing, lifting badly. Back pain causes include:

· bending awkwardly

· lifting, carrying, pushing or pulling incorrectly

· slouching in chairs

· standing or bending down for long periods

· twisting

· over-stretching

· driving in a hunched position

· driving for long periods without taking a break

Sometimes the pain develops suddenly for no apparent reason. Some people just wake up one morning with back pain and have no idea what has caused it.

Risk factors

Some risk factors increase the risk of developing back pain. These include:

· being overweight  – the extra weight puts pressure on the spine. Use the healthy weight BMI calculator to find out if you need to lose weight. 

· smoking – this could be due to tissue damage in the back caused by smoking or the fact that smokers tend to have unhealthier lifestyles than non-smokers. Get help quitting. 

· being pregnant – the excess weight of carrying a baby can place additional strain on the back

· long-term use of medication that is known to weaken bones, such as corticosteroids.

· stress – it is thought stress can cause tension the muscles of the back, which can result in back pain.
