A herniated disc occurs when the soft cushions between your spinal vertebrae become compressed and shift out of place. This displacement can put pressure on nearby nerves, leading to symptoms like back pain, tingling, or numbness in the limbs.
The most frequent cause of this condition is the gradual weakening and dehydration of spinal discs that happens as the body ages naturally. It can also develop due to physical trauma, poor posture, or repeated strain on the spine.
Disc herniation can occur in the cervical, thoracic, or lumbar regions of the spine. An orthopedic doctor typically oversees treatment, which may involve medication, physical therapy, or surgical intervention for more serious cases.
Main symptoms
The primary symptoms of a herniated disc include:
-
Neck pain that may spread to the shoulder, arm, or hands;
-
Pain in the middle of the back that might also affect the ribs;
-
Lower back pain or pain following the path of the sciatic nerve, affecting the buttocks, thighs, legs, and heel;
-
Difficulty with neck range of motion or leg movement;
-
Tingling sensations or a loss of strength in the arms, hands, legs, or feet;
-
Changes in bladder or bowel function.
Symptoms can vary depending on which spinal vertebra is affected. The pain usually intensifies with movement and may worsen when coughing, laughing, or during bowel movements and urination. These issues can appear suddenly or gradually become more severe over time.
It is important to consult an orthopedic specialist if you experience these symptoms. They can perform necessary tests to confirm the diagnosis and determine the specific type of herniation to establish the most effective treatment plan.
Confirming a diagnosis
An orthopedic specialist begins the diagnostic process by evaluating your symptoms, health history, and physical condition.
Besides a physical exam, the doctor will likely order an X-ray to check the alignment of your spine and the condition of the vertebrae. They may also request an MRI or CT scan to assess the thickness of the disc, identify the exact location of the herniation, and determine its specific type.
Types of herniated discs
A herniated disc is classified by its location in the spine or the specific way the vertebral disc has changed shape.
Types by location
The condition is categorized based on the region of the spine where it occurs:
-
Cervical herniated disc: affects the neck area;
-
Thoracic herniated disc: affects the middle back;
-
Lumbar herniated disc: affects the lower back.
Identifying the exact location through imaging is vital so the specialist can recommend the correct course of treatment.
Types by disc deformity
Disc herniations are also classified by the shape of the intervertebral disc. The primary types are:
-
Protruding disc: the most common type, where the center of the disc remains contained but the disc has lost its normal oval shape;
-
Extruded disc: the center of the disc is deformed and pushes out, often taking on a teardrop shape;
-
Sequestered disc: the most severe stage, where the disc center is heavily damaged and may even break into separate pieces.
A sequestered disc often leads to the most intense symptoms due to the severity of the damage.
Possible causes
This condition results from a deformity in the intervertebral disc. As the disc loses its shape, it compresses nearby nerves, which triggers the associated symptoms.
Several factors can contribute to the development of a herniated disc, including:
-
Disc degeneration, dehydration, and weakening due to aging;
-
Chronic poor posture;
-
Genetic predisposition;
-
Obesity or carrying excess body weight;
-
A sedentary lifestyle;
-
Smoking;
-
Spinal trauma or previous injuries.
Other risk factors include frequently lifting heavy objects or working in jobs that require repetitive motions, such as nursing, dentistry, painting, or professional driving.
Herniated disc in pregnancy
If a herniated disc was diagnosed before pregnancy, symptoms might worsen while expecting. This often leads to intense back pain that can put pressure on nerve roots, including the sciatic nerve.
When the sciatic nerve is involved, a woman may feel pain in the back, the buttocks, or down the back of the thigh.
This occurs because progesterone increases the laxity of the body's ligaments during pregnancy. Since the spine is supported by ligaments, they become more elastic, which can allow vertebrae to shift slightly and aggravate an existing herniation or cause a new one.
During pregnancy, patients may use pain relievers or other medications specifically recommended by their obstetrician.
Treatment options
Treatment for a herniated disc is managed by an orthopedic specialist based on the severity, location, and symptoms of the case.
Generally, the recommended treatment plan includes:
-
Pain relievers and anti-inflammatories, such as ibuprofen, naproxen, or acetaminophen;
-
Muscle relaxants, such as cyclobenzaprine;
-
Opioids, such as codeine or tramadol, for more severe pain;
-
Nerve pain medications, such as gabapentin, pregabalin, or amitriptyline;
-
Corticosteroids, administered as injections directly into the spine by a specialist;
-
Physical therapy, utilizing specialized equipment, stretching, and custom exercises;
-
Structured exercise, such as postural re-education, hydrotherapy, or Pilates led by a physical therapist;
-
Surgery, reserved for cases where medication and physical therapy fail or when the herniation is exceptionally severe.
During recovery, patients are advised to avoid the activities that caused the injury, skip heavy exertion, and pause general physical activities.
