In fact, bad back is one of the most common health problems today, affecting people in all walks of lifE.The most recent available figures show that about a quarter of a million people are incapacitated with back pain every day. And many sufferers don't know the cause or the solution to their problem. The majority of our patients at the clinic tend to be women. They are especially vulnerable because of pregnancy but also because of osteoporosis, which I personally believe to be the major cause of problems for women. I have many women patients who say they have completely given up exercise because the pain makes them so miserablE.But of course that starts up a vicious circlE.Bed rest, giving up exercise and pain killers are traditional responses to back pain but, although there are many excellent drugs on the market, at our clinic we are beginning to realise the unique benefits of relaxation therapy.

Another problem is being overweight. Anyone a stone or more overweight who already has back pain is not doing himself any favours: though it won't actually set it off in the first place, the weight will increase the strain and make things worsE.The British diet could be partially to blame for the increase in back pain: over the last ten years the average weight of men has risen by 11 lbs. and of women by 9 lbs..
