Disc Herniation
What is Disc Herniation?
A disc herniation occurs when the soft, gel-like center, called the nucleus pulposus, of a spinal disc pushes through a tear or rupture in the disc's tougher outer layer, or annulus fibrosus. This can put pressure on nearby nerves, leading to pain, numbness, or weakness. Disc herniation can happen in any part of the spine but is most common in the lumbar, or lower back and cervical, or neck regions.
Lumbar Herniated Disc
A lumbar herniated disc occurs in the lower back, often affecting the sciatic nerve. The sciatic nerve runs from the lower back, through the hips, and down each leg, so herniation in this area can lead to pain in the lower back or legs.
Cervical Herniated Disc
A cervical herniated disc occurs in the neck. This type of herniation can affect nerves in the arms and shoulders, causing pain, numbness, or tingling in those areas.
Causes of Disc Herniation
Disc herniation can result from several factors, including:
- Aging: As people age, spinal discs lose water content, becoming more susceptible to tears and ruptures.
- Trauma or Injury: A sudden, improper movement or lifting a heavy object with improper form can cause a disc to herniate.
- Repetitive Strain: Repetitive motions, especially those involving the back or neck, can lead to wear and tear on the discs.
- Genetics: Some individuals may inherit a predisposition to developing herniated discs.
- Obesity: Excess body weight places added stress on the spine, increasing the risk of disc herniation.
Symptoms of Disc Herniation
The pressure of a herniated disc can lead to significant discomfort and mobility issues. Symptoms may vary in intensity and impact daily activities, depending on the location of the herniation.
The symptoms of disc herniation vary based on the location of the herniation:
Lumbar Herniated Disc:
- Lower back pain
- Pain radiating down one or both legs (sciatica)
- Numbness or tingling in the legs or feet
- Muscle weakness in the legs or feet
- Difficulty standing or walking
Cervical Herniated Disc:
- Neck pain
- Pain radiating into the shoulders, arms, or hands
- Numbness or tingling in the arms or hands
- Muscle weakness in the arms or hands
- Difficulty turning the head or holding the neck upright
Treatment Options for Disc Herniation
Treatment for disc herniation typically begins with conservative measures, but more invasive options may be needed depending on the severity of the condition. Talk to your doctor for a treatment plan if you suspect you may have a herniated disc.
Non-Surgical Treatments:
- Rest and Activity Modification: Limiting activities that exacerbate symptoms can allow the disc to heal.
- Physical Therapy: Strengthening and flexibility exercises can relieve pressure on the spine and promote recovery.
- Medications: Nonsteroidal anti-inflammatory drugs, or NSAIDs, muscle relaxants, or corticosteroids may be used to reduce pain and inflammation.
- Epidural Steroid Injections: Corticosteroids injected into the epidural space can reduce inflammation and provide temporary relief.
Surgical Treatments:
- Microdiscectomy: A minimally invasive procedure in which part of the herniated disc is removed to relieve pressure on the nerves.
- Laminectomy: Removal of part of the vertebrae (lamina) to create space and relieve pressure on the spinal cord or nerves.
- Spinal Fusion: In more severe cases, fusion of vertebrae may be necessary to stabilize the spine after disc removal.
Wondering Where Your Back Pain is Coming From?
Knowing if the pain is muscular or spinal will help your doctor identify the issue so the best treatment can be provided.
