Most people with back pain do not have any damage to their spine. It is surprisingly difficult to injure your spine. These are held in place by strong ligaments and powerful muscles. In most cases we cannot pinpoint the exact cause of the problem. X-rays usually don't help and expose the body to radiation.
Most back pain comes from the muscles, ligaments and joints.
Gentle exercise will return them to normal condition. Stress increases the amount of pain you feel. Tension causes muscle spasm and pain. Back pain often comes in spasms. It gets better over a few days then recurs, gradually returning to normal usually within 4 weeks.
