LUMBAR PAIN LOW OR WAIST PAIN: WHAT CAN BE?
It is estimated that 8 out of 10 people suffer at least one event of back pain throughout their life. Well established quickly and acutely (muscle-ligament distension), or produced slowly and chronic (osteoarthritis or herniated disc). Lumbar pain is caused in 97% of cases by an alteration of the vertebral machinery itself. Musculoskeletal disorders (50% of cases), and less frequent degenerative or age-related disorders, such as osteoarthritis (40%), disc herniation (4%), or stenosis of the vertebral canal (3%). Only 1% of cases of low back pain is attributable to non-mechanical causes, such as neoplasias or infection, and the remaining 2% is caused by visceral disorders (renal, pelvis, gastrointestinal or aortic aneurysms, among others) produce referred pain. Therefore, the cause of back pain in nine out of ten patients is due to an alteration in some muscle, ligament or joint. And although it is interesting to know this theoretical incidence, the practice should not be conditioned by these statistics, with anamnesis and exploration being the key way to reach the diagnosis.
