It can result from injury, activity and some medical conditions. Back pain can affect people of any age, for different reasons. As people get older, the chance of developing lower back pain increases, due to factors such as previous occupation and degenerative disk disease.
Lower back pain may be linked to the bony lumbar spine, discs between the vertebrae, ligaments around the spine and discs, spinal cord and nerves, lower back muscles, abdominal and pelvic internal organs, and the skin around the lumbar area.
The human back is composed of a complex structure of muscles, ligaments, tendons, disks, and bones, which work together to support the body and enable us to move around.
The segments of the spine are cushioned with cartilage-like pads called disks.
Problems with any of these components can lead to back pain. In some cases of back pain, its cause remains unclear.
The main symptom of back pain is an ache or pain anywhere in the back, and sometimes all the way down to the buttocks and legs.
Some back issues can cause pain in other parts of the body, depending on the nerves affected.
The pain often goes away without treatment, but if it occurs with any of the following people should see their doctor:
Back pain usually resolves with rest and home remedies, but sometimes medical treatment is necessary.
Over-the-counter (OTC) pain relief medication, usually nonsteroidal anti-inflammatory drugs (NSAID), such as ibuprofen, can relieve discomfort. Applying a hot compress or an ice pack to the painful area may also reduce pain.
Resting from strenuous activity can help, but moving around will ease stiffness, reduce pain, and prevent muscles from weakening.
If home treatments do not relieve back pain, a doctor may recommend the following medication, physical therapy, or both.
Medication: Back pain that does not respond well to OTC painkillers may require a prescription NSAID. Codeine or hydrocodone, which are narcotics, may be prescribed for short periods. These require close monitoring by the doctor. In some cases, muscle relaxants may be used.
Antidepressants, such as amitriptyline, may be prescribed, but research is ongoing at to their effectiveness, and the evidence is conflicting.
Physical therapy: Applying heat, ice, ultrasound, and electrical stimulation — as well as some muscle-release techniques to the back muscles and soft tissues — may help alleviate pain.
As the pain improves, the physical therapist may introduce some flexibility and strength exercises for the back and abdominal muscles. Techniques for improving posture may also help.
The patient will be encouraged to practice the techniques regularly, even after the pain has gone, to prevent back pain recurrence.
Exercise: Regular exercise helps build strength and control body weight. Guided, low-impact aerobic activities can boost heart health without straining or jerking the back. Before starting any exercise program, talk to a health care professional.
There are two main types of exercise that people can do to reduce the risk of back pain:
Diet: Make sure your diet includes enough calcium and vitamin D, as these are needed for bone health. A healthful diet also helps control body weight.
Smoking: A significantly higher percentage of smokers have back pain incidences compared to non-smokers of the same age, height, and weight.
