UNDERSTANDING BACK PAIN CAUSES AND TREATMENT

Back pain affects nearly 80% of Americans and the most common form is Low Back Pain. Because you rely on your back for almost every move you make, it is vulnerable to injury. Back pain can even be disabling. It is one of the most common problems prompting a visit to your doctor and for missing work. In fact, it is the second highest cause of disability in persons under the age of 45.

Although people complain of back pain, it is not a diagnosis but rather a symptom of an underlying disorder. There are two types of back pain, acute and chronic. Acute back pain is pain with a new onset. It comes on suddenly, usually due to injury. This is the most common type of back pain. It is usually resolved in less than one month but no more than 6 weeks duration. Chronic pain is pain that can have a quick or slow onset, but it lingers for long periods of time. Although it may last three months or longer, some people experience a lifetime of chronic back pain. Chronic pain is the least common type of pain.


What Causes Back Pain?
To begin to understand the causes of back pain, we need to R├╝ckenschmerzen understand the spine. The back is made up of 33 vertebrae or bones. It is divided into 5 groups: Cervical, Thoracic, Lumbar, Sacrum and Coccyx. The cervical spine (upper back or neck) consists of 7 vertebrae. The thoracic(middle back) has 12, and the lumbar spine(low back) has 5 vertebrae. The sacrum consists of 5 fused vertebrae, and the coccyx(tail bone) has 4 vertebrae fused together.

The vertebrae are held together by ligaments and muscles with discs between the vertebrae. The discs are filled with a jellylike center, allowing them to act like a shock absorber. The vertebrae link together to provide stability and support. They protect the spinal cord and spinal nerves that run through the spinal canal.

Because the neurological system is complex, it is difficult to pinpoint the exact cause of back pain. The causes of back pain are divided into categories: Mechanical, Injuries, Acquired disorders or diseases, Infections or tumors.

Mechanical causes: These are problems with how the spine works. For example, Spondylolistesis(deterioration of the disc one vertebrae to slip forward over another, causing the vertebrae to rub together, therefore causing pain). Other mechanical problems are fractures, herniated discs, spinal stenosis, spinal degeneration and sciatica.

Injuries- This category includes common forms of back pain due to injury to the spine or the ligaments and muscles involved with the spine. Sprains, for example, result if a ligament that supports the spine is pulled or torn due to improper lifting or body mechanics, even twisting the wrong way, Fractures can occur from osteoarthritis which causes the bones to become brittle and weak. Sever injuries can result from an accident or fall.

Acquired disorders- These are medical problems that you might have been born with such as scoliosis(an abnormal curvature of the spine) to other problems that you acquired, such as arthritis(osteoarthritis and rheumatoid arthritis) which can lead to fractures; musculoskeletal pain syndromes such as fibromyalgia, spinal stenosis (Narrowing of the spinal canal putting pressure on spine or nerves); and even pregnancy.

Infection/Tumors- Infection, although not common, can cause pain if it involves the vertebrae. Two examples of this are Osteomyelitis(infection and inflammation of the vertebrae) and Discitis(infection in the discs).Tumors, although rare, can also cause back pain. These can be benign or cancerous, but usually result from a tumor that has spread from another area of the body.


How is back pain diagnosed?
In order for your physician to discuss the proper treatment for your back pain, he will need to do a thorough medical history and physical exam. You will need to give a clear concise description of your pain. Your physician will need to know how the pain started, what you were doing when it started, how severe it is, does it come and go or is it constant, and what makes the pain better or worse. You will need to undergo some diagnostic tests. Common tests done to diagnose back pain are x-rays, bone scans, and MRI’s. These diagnose problems due to bone or soft tissue injuries. Your doctor may order blood and urine tests to look for infection. If your physician feels the pain might be caused by a nerve problem, then you will have an EMG(electromyography) or nerve study. An EMG is an assessment of the electrical impulses of nerves and the response of the muscles.


How is Back Pain Treated?
The common goals of treatment are to relieve back pain and to restore mobility. Treatment varies depending on the severity and type of injury. The most common and basic treatment used for strains or minor injury is Rest. Heat can be used to promote circulation to the area and relieve spasms. Cold packs can be used to decrease the swelling in the affected area of the back. Common OTC (over the counter) medications such as Aspirin, Motrin, Tylenol, and Aleve are prescribed to help the pain and inflammation.

Long term bed rest is not usually recommended because it can make recovery slower and can ultimately cause other problems. Usually the doctor will have you gradually resume normal activities after 24-72 hours of rest. He may start you on a physical therapy program which should include heat, massage, ultrasound and an individualized exercise regimen. If the pain does not subside and it is interfering with your normal daily activities, your doctor may order prescription pain medications such as Darvocet, Vicodin, or Percocet and anti-inflammatory agents to relieve muscle spasm.

If your pain becomes chronic and all other treatments have failed, your doctor may refer you to a Back or Pain specialist. Because the back is a complex entity, specialists are more up to date on new advances in the treatment of back pain. Some treatments you might encounter are epidural nerve block (injection of anesthetic, anti-inflammatory, or steroid into the epidural space of the back for long term pain relief)and trigger point injections(injection of steroids and anesthetic into the muscle that is triggering pain.)This should also provide long term pain relief. Other medications such as antidepressants and anticonvulsants have been found to help relieve pain caused by nerve injuries.
