Degenerative conditions in the vertebrae of your lumbar spine, or low back, are a common source of leg pain.
If you are experiencing leg pain, the source of your discomfort may not actually be in your leg, but in your lower back, or lumbar spine. The lumbar spine is a common source of back pain because it bears more body weight than any other section of the spine and is also subject to a significant amount of stress and force, be it from lifting a load of laundry or blocking a tackle.
When you feel pain, it’s a reaction to signals transmitted throughout your body. These signals are sent from the pain source through the nerves in the spinal cord and into the brain, where they are perceived as pain. Problems that originate in the lumbar spine may result in pain and other symptoms, such as tingling, numbness and muscle weakness, which may be localized in the lower back and/or extend into the hips, buttocks and/or legs. The medical term for symptoms that radiate into the extremities is radiculopathy, derived from the Latin words “radix,” or roots, and “pathos,” which means disease.
Acute pain is commonly described as sharp and severe; it tends to come on suddenly but also improve with time and short-term conservative treatment, such as medication, exercise, physical therapy or rest.
Chronic pain is commonly described as a deep, aching, dull or burning pain, and may be accompanied by numbness, tingling and/or weakness that extends into the extremities. Chronic pain tends to last a long time and is not relieved by conservative care.
The five vertebrae of the lumbar spine (L1-L5), located directly below the thoracic spine (mid-back) and directly above the sacrum, are separated by shock-absorbing intervertebral discs and supported by muscles and ligaments. These discs are very important for the normal mobility and function of your back. Over time, age, genetics and everyday wear-and-tear can contribute to deterioration of these discs, which, when healthy, act as “cushions” for the individual bones of the spine, or vertebrae.
Each disc is made up of two parts:
Over time, intervertebral discs can become dried out, compressed or otherwise damaged, due to age, genetics and everyday wear-and-tear. When this happens, the nucleus pulposus may push through the annulus fibrosis. Disc degeneration also may result in bone spurs, also called osteophytes, or spinal stenosis, the narrowing of the area of the spine where the nerve leaves the spine and travels to the rest of the body.
If disc or bone material pushes into or impinges on a nearby nerve root and/or the spinal cord, it may result in pain, numbness, weakness, muscle spasms and loss of coordination, both at the site of the damage and elsewhere in the body. Sciatica – often described as pain that begins in the hip and buttocks and continues all the way down the leg – is one example of a radicular symptom that may be caused by damage or deterioration in the lumbar spine.
These symptoms and the conditions that cause them are collectively referred to as degenerative disc disease, if the condition has become chronic over time. Similar symptoms, however, may occur suddenly if the disc nucleus dislodges acutely and causes nerve root compromise, a condition referred to as a herniated disc.
If you are suffering from chronic leg, buttock or hip pain or pain as a result of a physical trauma involving your lower back, such as a fall or car accident, you should seek treatment from a physician.
Consult a physician immediately if you:
If you are experiencing leg pain, talk to your doctor about appropriate treatment options. Identifying the cause of your leg pain, alleviating the pain – either at home or with your physician’s help – and avoiding re-injury are key to the healing process.

If you are experiencing arm pain, the source of your discomfort may not actually be in your arm, but in your neck. The neck, or cervical spine, is made up of seven vertebrae separated by shock-absorbing intervertebral discs and supported by muscles and ligaments, and also is rich in spinal nerves and nerve roots.
When you feel pain, it’s a reaction to signals transmitted throughout your body. These signals are sent from the pain source through the nerves in the spinal cord and into the brain, where they are perceived as pain. Problems that originate in the cervical spine may result in pain and other symptoms, such as tingling, numbness and muscle weakness, which may be localized in the neck and/or extend into the shoulders, arms and hands. The medical term for symptoms that radiate into the extremities is radiculopathy, derived from the Latin words “radix,” or roots, and “pathos,” which means disease.

When this happens, the nucleus pulposus may push through the annulus fibrosis. Disc degeneration also may result in bone spurs, also called osteophytes, or spinal stenosis, the narrowing of the area of the spinal canal.
If disc or bone material pushes into or impinges on a nearby nerve root and/or the spinal cord, it may result in pain, numbness, weakness, muscle spasms and loss of coordination, both at the site of the damage and elsewhere in the body, since most of the nerves for the rest of the body (e.g., arms, chest, abdomen and legs) pass from the brain through the neck.
These symptoms and the conditions that cause them are collectively referred to as degenerative disc disease, if the condition has become chronic over time. Similar symptoms, however, may occur suddenly if the disc nucleus dislodges acutely and causes nerve root compromise, a condition referred to as a herniated disc.

The cervical spine is designed to handle a great deal of stress; however, there are a number of degenerative changes that can take place in the vertebrae and discs, resulting in neck pain and other symptoms.
Neck pain and other symptoms caused by a cervical (neck) spine disorder are a very common problem for many adult Americans. The neck, or cervical spine, is made up of seven vertebrae separated by shock-absorbing intervertebral discs and supported by muscles and ligaments, and also is rich in spinal nerves and nerve roots.
When you feel pain, it’s a reaction to signals transmitted throughout your body. These signals are sent from the pain source through the nerves in the spinal cord and into the brain, where they are perceived as pain. In addition to causing neck pain, problems that originate in the cervical spine may result in pain and other symptoms, such as tingling, numbness and muscle weakness, which extend into the shoulders, arms and hands.
Acute pain is commonly described as sharp and severe; it tends to come on suddenly but also improve with time and short-term conservative treatment, such as medication, exercise, physical therapy or rest.

Back pain is the body’s natural response to injury or degenerative conditions of the spine. Usually, it’s resolved by time and non-surgical treatment, but it’s also important to know which conditions warrant a call to the doctor.
The back is one of our most important anatomic structures, providing support and facilitating mobility and balance for the entire body, as well as protecting the spinal cord. Because of the loads placed on it each and every day, it’s no surprise this well-designed structure, consisting of bones (vertebrae), discs, muscles, tendons, ligaments and nerves, is particularly susceptible to injury and other conditions that may have you reaching for the heating pad – or your doctor’s phone number.
When you feel pain, it’s your body’s natural reaction to signals transmitted from the pain source, which travel through the nerves in the spinal cord and up to the brain, where they are perceived as pain.
Acute pain is commonly described as sharp and severe; it tends to come on suddenly but also improve with time and short-term conservative treatment, such as medication, exercise, physical therapy or rest.
Chronic pain is commonly described as a deep, aching, dull or burning pain, and may be accompanied by numbness, tingling and/or weakness that extends into the extremities. Chronic pain tends to last a long time and is not relieved by conservative care.
Many sudden attacks of acute back pain are the result of overstretched muscles (strains) or ligaments (sprains). The pain may be most severe immediately after injury, or it may worsen gradually over a few hours. In most instances, back pain as a result of strain or sprain can be resolved following a conservative course of treatment – usually within two to six weeks – provided there are no serious underlying medical conditions.
Common causes of strains and sprains that can trigger acute back pain include:
Physical conditions that can possibly contribute to the onset of acute back pain include:
Other causes of back pain include:
Mechanical Disorders: Many people who suffer from back problems are experiencing mechanical pain, which means that a specific part of their spine, such as an intervertebral disc, a ligament, or a joint is damaged and is not working correctly. Examples of spinal mechanical disorders include degenerative disc disease, herniated disc, spondylolysis/spondylolysthesis, arthritis and spinal stenosis.
Developmental Disorders: Developmental disorders of the lower back are caused by abnormalities in the formation and growth of the skeleton. Although the treatment for many of these conditions is conservative, surgery may be required to keep some disorders from worsening, and in order to prevent long-term disability and or deformity. Scoliosis and kyphosis are examples of developmental disorders of the spine.
Inflammatory and Infectious Disorders: Infections of the spinal column are not common, but they are important because they are difficult to diagnose and there are serious consequences in the delay of an accurate diagnosis.
Tumors: Cancers and tumors of the spine and spinal cord are relatively rare. The most common symptom that patients with a spinal tumor have is pain. Because back pain is very common, it is also not a specific symptom of any one disease or medical condition.
Trauma: Trauma to the spine refers to injury that has occurred to the bony elements, soft tissues and/or neurological structures, resulting in instability of the vertebral column and actual or potential neurological injury.
