While the spine is a resilient part of the body, it experiences wear and tear throughout a person’s life. Unfortunately, this strain and pressure may lead to various spinal conditions, including a herniated disc.
The spine is a complex collection of bones, cartilage and nerves. Three natural curves create an S shape, which helps absorb shock and protect it from injury. The spine also comprises 33 vertebrae, intervertebral discs, facet joints, spinal nerves and soft tissues, allowing the body to stand upright and move freely.
A herniated disc is damage or an injury to the spinal column. There is a round cushion between each vertebra known as the spinal discs, which serve as a buffer. These discs prevent the vertebrae from grinding against one another when you move. A herniated disc happens when one of these discs experiences a tear, damage or leak. Other names for a herniated disc include bulging disc, protruding disc, slipped disc, pinched nerve or a ruptured disc.
These terms indicate damage or injury to the spinal disc, causing back or neck pain. A herniated disc can cause two types of pain — disc-related pain or a pinched nerve. The spinal disc itself may be causing discomfort or pain if it causes spinal instability, known as degenerative disc disease.
Degenerative disc pain often causes a low-level, constant pain around the disc with occasional episodes of severe pain. A herniated disc in the lower back may also cause pain from a pinched nerve. In cases of a pinched nerve, the disc itself is not painful, but it may be compressing a nearby spinal nerve.
A damaged spinal disc may leak fluid, causing nearby nerves to inflame or become irritated, which results in radicular pain or nerve root pain. Radicular pain often causes shooting, sharp pain that can radiate throughout the body, including down the legs and arms.
Research finds approximately five to 20 individuals per 1000 adults experience a herniated disc, most commonly in the 30 to 50 age group.
There are two main causes of a herniated disc — age and trauma. Age is a leading factor in disc herniation. With age, the spinal discs begin to gradually lose fluid, a condition known as degenerative disc disease. Wear and tear on the spinal discs cause tears and cracks on the disc’s outer layer, where the interior fluid may leak from.
Trauma is another common cause of disc herniation. When the spinal disc is damaged, torn or overstressed, it can rupture because of high-impact trauma, such as a fall, collision or car accident. For example, a herniated neck disc may develop following a sports injury. Risk factors that may increase a person’s risk of developing a herniated disc include:
While a herniated disc can develop within any spinal disc, they are most common within the lower back, as the lower spine often experiences more wear, tear and stress. Ninety-five percent of patients with a herniated disc between 25 to 55 years old experience disc-related complications of the lower lumbar spine.
Herniated disc symptoms vary depending on the severity and where the injured disc is located. It is also possible to have a herniated disc with no pain because not all herniated discs cause noticeable symptoms. Some of the most common herniated disc symptoms include:
A spinal specialist may recommend several tests to diagnose a herniated disc properly. Two of the most common herniated disc diagnosis tests include:
After a physician diagnoses a herniated disc, they will discuss potential treatment options to improve herniated disc symptoms or minimize the risk of the herniated disc from worsening or causing severe symptoms in the future. Some of the most common and effective herniated disc treatments include:
