Because approximately 80% of people have been recorded with back pain at one time or another, it is considered the second most common reason people choose to visit the doctor's office. Because the lower back is such an unstable part of the spine, it means it is much more susceptible to injury and pain. Sprained ligaments, ruptured disks, strained muscles, poor posture, stress, and obesity can cause pain in your lower back. In order to properly heal your back, chiropractors may simply adjust your lower lumbar vertebrae and pelvis. Other treatments (muscle relaxants, pain killers, etc.) only treat the symptoms of your problems, while Chiropractic actually focuses on the problem itself! Studies have even shown that Chiropractic care is not only more effective, but also much less expensive.
