Low back pain - chronic
Low back pain refers to pain that you feel in your lower back. You may also have back stiffness, decreased movement of the lower back, and difficulty standing straight.
Low back pain that is long-term is called chronic low back pain.
Causes
Low back pain is common. Almost everyone has back pain at some time in their life. Often, the exact cause of the pain cannot be found.
A single event may not have caused your pain. You may have been doing many activities, such as lifting the wrong way, for a long time. Then suddenly, one simple movement, such as reaching for something or bending from your waist, leads to pain.
Many people with chronic back pain have arthritis. Or they may have extra wear and tear of the spine, which may be due to:
- Heavy use from work or sports
- Injuries or fractures
- Surgery
You may have had a herniated disk, in which part of the spinal disk pushed onto nearby nerves. Normally, the disks provide space and cushion in your spine. If these disks dry out and become thinner and more brittle, you can lose movement in the spine over time.
Herniated disk
A herniated (slipped) disk occurs when all or part of a disk is forced through a weakened part of the disk. This may place pressure on nearby nerves...

You might have heard a friend say that they have slipped a disk. Or, you may have slipped a disk yourself during an overly strenuous workout, or by straining while lifting something heavy. A slipped disk can be painful, so painful, in fact, that you can barely move. But what exactly is a slipped disk? And what can you do about it if you have one? This is your spine. In between the bones, which are called vertebrae, are little cushioning disks. These disks not only allow you to bend and move but also prevent your bones from rubbing against each other. Sometimes an injury can push a disk out of place, producing a bulge. This bulge is called a herniated disk. Or, a disk may break open. When a disk moves, it puts pressure on nearby nerves, and that's when you start to feel pain. Most slipped disks are found in the lower back or lumbar region, although you can also have one in your neck, or cervical region. When you have a slipped disk, you'll hurt, but often just on one side of your body. If the disk is in your lower back, you may feel a sharp pain in one part of your leg, hip, or buttocks. Your leg may also feel weaker than usual. If the disk is in your neck, the pain and numbness can stretch all the way from your neck down to your shoulder and arm. You may notice that it hurts even more when you stand for a long period of time, or if you sneeze, cough, or laugh. So, how do you treat a slipped disk? First your doctor will want to make sure that you actually have a slipped disk. To find out, the doctor will check your muscle strength, feeling, and reflexes, and have you move in different ways, for example, by bending, standing, and walking. You may also have a scan to find the exact location of the slipped disk. While bed rest was once the standard therapy for low back pain, studies show that for most people it does not help and may even make the situation worse. Rapid return to healthy normal activity is usually best, being careful not to put too much stress on the back. While you're doing that, you can take medicines like ibuprofen or aspirin to relieve the pain. Muscle relaxants may also help. Acupuncture, massage, and yoga have also been shown to be affective in some studies. Physical therapy may be helpful after the first two or three weeks. It can help strengthen the muscles of your spine, and teach you how to move properly so you don't injure yourself again. If these measures don't help, your doctor may suggest getting steroid injections into the area where you slipped the disk, to reduce pain and relieve swelling. As a last resort when all other treatments have failed, you may have a surgery called a diskectomy to remove the damaged disk. You may be in pain now, but don't despair, with treatment it should ease. Realize that it may take a few months before you're back to your old self. Don't try to overdo it by bending or doing any heavy lifting. You'll just wind up back on your couch, hurting again.
If the spaces between the spinal nerves and spinal cord become narrowed, this can lead to spinal stenosis. These problems are called degenerative joint or spine disease.

Spinal stenosis is narrowing of the spinal canal. This can develop as you age from drying out and shrinking of the disk spaces. (The disks are 80% water.) If this happens, even a minor injury can cause inflammation of the disk and put pressure on the nerve. You can feel pain anywhere along your back or leg(s) that this nerve supplies.
Other possible causes of chronic low back pain include:

- Sharp pain
- Tingling or burning sensation
- Weakness in your legs or feet
Low back pain can differ from person to person. The pain may be mild, or it can be so severe that you cannot move.
Depending on the cause of your back pain, you may also have pain in your leg, hip, or on the bottom of your foot.
Exams and Tests
During the physical exam, the health care provider will try to pinpoint the location of the pain and figure out how it affects your movement.
Other tests you have depend on your medical history and symptoms.
Tests may include:
- Blood tests, such as a complete blood count and erythrocyte sedimentation rate

In some patients, a spinal cord stimulator can help reduce back pain.
Other treatments that may be recommended if your pain does not improve with medicine and physical therapy include:
- Spinal surgery, only if you have nerve damage or the cause of your pain does not heal after a long time
- Spinal cord stimulation, in which a small device sends an electric current to the spine to block pain signals
