If you suffer from low back pain, know that you are certainly not alone. In general, back pain is due to either a traumatic injury, or the normal wear and tear from age.
Pain can range from mild to severe. In some cases, pain can make it difficult or impossible to walk, sleep, work or do everyday activities.
Usually, lower back pain gets better with rest, pain relievers and physical therapy (PT). Cortisone injections and hands-on treatments (like osteopathic or chiropractic manipulation) can relieve pain and help the healing process. Some back injuries and conditions require surgical repair.
How common is lower back pain?
Around four out of five people have lower back pain at some point in their lives. It’s one of the most common reasons people visit healthcare providers.
Some people are more likely to have lower back pain than others. Risk factors for lower back pain include:
- Age: People over 30 have more back pain. Disks (soft, rubbery tissue that cushions the bones in the spine) wear away with age. As the disks weaken and wear down, pain and stiffness can result.
- Weight: People have overweight/obesity or carry extra weight are more likely to have back pain. Excess weight puts pressure on joints and disks.
- Overall health: Weakened abdominal muscles can’t support the spine, which can lead to back strains and sprains. People who smoke, drink alcohol excessively or live a sedentary lifestyle have a higher risk of back pain.
- Occupation and lifestyle: Jobs and activities that require heavy lifting or bending can increase the risk of a back injury.
- Structural problems: Severe back pain can result from conditions, such as scoliosis, that change spine alignment.
- Disease: People who have a family history of osteoarthritis, certain types of cancer and other disease have a higher risk of low back pain.
- Mental health: Back pain can result from depression and anxiety.
What are the symptoms of lower back pain?
Pain may be sharp, dull, aching, or throbbing. The pain may radiate to your bottom or down the back of your legs (sciatica). Pain is often worse in certain positions (like bending over, sitting or standing for too long) and gets better when you lie down.
Other symptoms of lower back pain include:
- Stiffness: It may be tough to move or straighten your back. Getting up from a seated position may take a while, and you might feel like you need to walk or stretch to loosen up. You may notice decreased range of motion.
- Posture problems: Many people with back pain find it hard to stand up straight. You may stand “crooked” or bent, with your torso off to the side rather than aligned with your spine. Your lower back may look flat instead of curved.
- Muscle spasms: After a strain, muscles in the lower back can spasm or contract uncontrollably. Muscle spasms can cause extreme pain and make it difficult or impossible to stand, walk or move.
What causes lower back pain?
Many injuries, conditions and diseases can cause lower back pain. They include:
- Strains and sprains: Back strains and sprains are the most common cause of back pain. You can injure muscles, tendons or ligaments by lifting something too heavy or not lifting safely. Some people strain their back by sneezing, coughing, twisting or bending over.
- Fractures: The bones in the spine can break during an accident, like a car crash or a fall. Certain conditions (such as spondylolysis or osteoporosis) increase the risk of fractures.
- Disk problems: Disks cushion the vertebrae (small spinal bones). Disks can bulge from their position in the spine and press on a nerve. They can also tear (herniated disk). With age, disks can get flatter and offer less protection (degenerative disk disease).
- Structural problems: A condition called spinal stenosis happens when the spinal column is too narrow for the spinal cord. Something pinching the spinal cord can cause severe sciatic nerve pain and lower back pain. Scoliosis (curvature of the spine) can lead to pain, stiffness and difficulty moving.
- Arthritis: Osteoarthritis is the most common type of arthritis to cause lower back pain. Ankylosing spondylitis causes lower back pain, inflammation and stiffness in the spine.
- Disease: Spine tumors, infections and several types of cancer can cause back pain. Other conditions can cause back pain, too. These include kidney stones and abdominal aortic aneurysm.
- Spondylolisthesis: This condition causes the vertebrae in the spine to slip out of place. Spondylolisthesis leads to low back pain and often leg pain as well.
