However, you need to have the proper diagnosis and determine the cause of the low back pain before deciding on any type of therapeutic intervention. Meaning, chiropractics work better for mechanical dysfunction such as improperly aligned vertebral bodies or facet joints. If the cause of the pain is the facet joint or a malaligned vertebral body pushing on a herniated disc or nerve root, then it's often very appropriate. My personal recommendation as physician and patient is that if chiropractics or acupuncture don't provide any benefit in the first two treatments, they are very unlikely to provide any long term benefit, and treatment should be terminated. Most patients that benefit from this type of therapy see significant difference within the first one to two treatments.
Further treatment is a waste of money and time.
Generalized low back pain associated with muscle strain is usually not going to be successfully treated with these therapies or interventions. The best sleeping position really should be determined by the cause of the low back pain. Older patients with spinal stenosis prefer to sleep on their backs with their back bent a little or on their side with their knees up. Patients with facet injuries or arthritis of the facet joint also prefer this position. Patients with herniated disc in their back like to sleep flat on their back with knees supported by pillows.
