Lower back pain, used to be called lumbago; as this area is known as the lumbar region of the back. Initial investigation is needed to ensure it is not a freshly torn muscle and the exact nature and position of the damage. The body has a trick of making us feel pain in a place different from the actual damage. These investigations should ensure that the pain is not caused by Kidney or Liver problems and then try to find if the damage is in the spine, the hip joints or the muscles surrounding the skeleton. There are several layers of different muscles all acting in this area (so called deep and superficial muscular structures) and each structure is made up of many interconnected but separate muscles. Establishing exactly where the pain is coming from, how deep etc is difficult and often seems to move, one day being a few inches away from yesterdays etc.
