There are many causes of back pain; fortunately, the more serious problems are relatively rare and generally diagnosed by conventional medicine. In such cases the symptoms are usually quite different from the norm and appropriate caution can be exercised. The past history of any back trouble gives valuable clues as to what the cause of any pain is.
There may be a history of back trouble going back many years which has recently become worse, and/or it may be linked to a more traumatic incident like a fall or a road traffic accident, either recently or sometime in the past. Any recent trauma may often mean that there is some actual damage, which will take time to heal as well as the normal back problem. Quite often the underlying back problem relates back to the first ever twinge, niggle and/or stiffness which may be many years prior to the first main occurrence of back pain.
The more common troubles are basically caused by a very small lateral twist in one or several of the vertebrae, usually so slight that it does not show up in x-rays and can therefore remain undetected by conventional means.
