Low back pain affects 60-80% of adults at some point and is usually caused by minor trauma or injury to back muscles or spinal disks. Common causes include degenerative disk disease and arthritis of the spine. Symptoms include lower back pain that may radiate to the buttocks or legs, along with difficulty standing, sitting, or walking. Treatment options include medications, physical therapy, chiropractic care, acupuncture, massage, yoga, and exercise to relieve pain and improve back muscle strength and flexibility.
