Low Back Pain
Many things can cause low back pain. Some causes are:
- Muscle strains or ligament sprains
- Degenerative disc disease—wear and tear on discs in the spine
- Structural problems in the spine
- Other health problems, such as osteoporosis
Health problems that can also cause back pain include:
- Herniated disc —the cushions between the bones of the spine develop a bulge
- Degenerative diseases, such as arthritis
- Fractures due to trauma and osteoporosis
- Spinal stenosis—narrowing of the spinal canal
- Spondylolisthesis—slippage of a bone in the lower back
- Ankylosing spondylitis—an autoimmune disease involving the spine
- Cauda equina syndrome—compression of nerve roots at the base of the spinal cord
This problem is more common in older adults but can happen at any age. Things that may increase the risk of injury are:
- Certain activities, such as lifting, bending, or twisting
- Lack of activity
- Prior back injury
- Prior back surgery
- Anxiety and depression
Job-related strain, such as:
- Bending, twisting, or reaching
- Heavy manual labor
- Repetitive tasks
The back pain may be constant or come and go. It may be worse with motion, sitting, standing, bending, and twisting. If a nerve is irritated, the pain may spread into the buttock or leg on one side. Muscle weakness or numbness may also occur.
When Should I Call My Doctor?
Some problems may need care right away. Call the doctor if you have:
- Severe or worsening pain
- Pain that lasts longer than one week
- Problems walking, standing, or moving
- Pain that is worse at night or when you lie down
- Pain that spreads down your legs
- Pain or throbbing in your belly
Back pain with:
- Numbness, weakness, or tingling in the buttocks, genitals, or legs
- Loss of bowel or bladder control
- Problems urinating
- Fever, unexplained weight loss, or other signs of illness
Back pain often improves with home care and time. If the pain is new, steps that may help to ease pain include:
- Staying away from movement that makes pain worse—absolute rest is rarely helpful.
- Cold or hot compresses over the area
- Medicines, such as:
- Over the counter and prescription pain relievers
- Topical pain relievers that are applied to the skin
- Muscle relaxants to ease spasms
- Avoid intense stretching or exercise
- Physical therapy to improve strength, flexibility, and range of motion
- Cognitive behavioral therapy to learn how to manage pain
Back pain can linger for longer periods of time. Steps that may help chronic back pain include:
- Regular exercise program—avoid activities that make back worse
- Stretching program, like yoga
- Physical therapy—to improve strength and balance, find cause of problem
- Heat when back is stiff
Other treatments that may be helpful include:
- Spinal manipulation—specialist move spinal bones with controlled thrusts
Surgery may be needed for pain that is making day to day life difficult. Other treatments will be tried first before surgery. The type of surgery will depend on what is causing pain. Choices include:
- Discectomy—remove damaged tissue between spinal bones, can relieve pressure on nerves.
- Laminectomy—part if spinal bone is removed to ease pressure on nerves.
- Spinal fusion—2 or more spinal bones are fused.
