Lumbar vertebrae

• Small fractures to the spine from osteoporosis
• Muscle spasm (very tense muscles that remain contracted)
• Ruptured or herniated disk
• Degeneration of the disks
• Poor alignment of the vertebrae
• Spinal stenosis (narrowing of the spinal canal)
• Strain or tears to the muscles or ligaments supporting the back
• Spine curvatures (like scoliosis or kyphosis) which may be inherited and seen in children or teens
• Other medical conditions like fibromyalgia

Low back pain from any cause usually involves spasms of the large, supportive muscles alongside the spine. The muscle spasm and stiffness accompanying back pain can feel particularly uncomfortable.

You are at particular risk for low back pain if you:

• Work in construction or another job requiring heavy lifting, lots of bending and twisting, or whole body vibration (like truck driving or using a sandblaster)
• Have bad posture
• Are pregnant
• Are over age 30
• Smoke, don't exercise, or are overweight
• Have arthritis or osteoporosis
• Have a low pain threshold
• Feel stressed or depressed

• Bladder infection
• Kidney stone
• Endometriosis
• Ovarian cancer
• Ovarian cysts
• Testicular torsion (twisted testicle)
