What is Sciatica Pain?

Understanding Sciatica Pain: Diagnosis and Risk Factors

Sciatica pain is a common and yet excruciating condition that affects many individuals worldwide. It is the pain caused by irritation or pressure on the sciatic nerve, the longest nerve in the human body, which runs from the lower back down through the hips and buttocks and into each leg. 

People with sciatica pain frequently feel severe, stinging pain, which could be accompanied by a sensation of numbness, tingling, or weakness in the affected leg. Keep reading to learn the causes, symptoms, diagnosis, and medications to manage the condition effectively!

Causes of Sciatica Pain

Mentioned below are the common causes that lead to this condition: 

●  Bulging or Herniated Disc

A bulging or herniated disc is the most frequent cause of sciatica pain, occurring in most cases. The intervertebral discs that act as shock absorbers for the spine can become dry, weaken, or rupture as a result of ageing or injury. 
When a disc bulges or when the jelly-like nucleus leaks out, it may put pressure on the sciatic nerve, resulting in pain, inflammation, and irritation.

●  Spinal Stenosis

Spinal stenosis is the narrowing of spaces in the spine, which usually occurs due to ageing or degenerative changes. A narrowed spinal canal may exert pressure on the sciatic nerve, causing pain, numbness, and paresthesia.

●  Bone Spur

Bone spurs are bony growths frequently caused by spinal osteoarthritis. This condition results in cartilage loss, which stimulates the immune system to stimulate new bone growth. Spurs may impinge on the sciatic nerve roots, generating localized pain and discomfort.

●  Spondylolisthesis

Spondylolisthesis occurs when a vertebra slides forward over the one beneath it. This displacement can compress the sciatic nerve or its roots, resulting in stabbing pain in the lower back and legs.

●  Traumatic Injury

Trauma from automobile accidents, falls, or sports injuries can directly injure or compress the sciatic nerve. Fractures, dislocations, or penetrating trauma such as bullet or knife wounds can result in nerve inflammation and sciatica symptoms.

Risk Factors Causing Sciatica Pain

Although sciatica pain can occur in anyone, some factors raise the risk of developing the condition.

• Age: Sciatica is more frequent in individuals between the ages of 30 and 50, as degenerative spinal changes increase with age.
• Weight: Being overweight or pregnant puts added pressure on the spine, which increases the risk of disc herniation and compression of the sciatic nerve.
• Diabetes: This metabolic disorder can cause nerve damage, so people are at greater risk of developing sciatica and other neuropathies.
• Occupation: Lifting heavy items, sitting or standing for long periods, or repetitive movements may strain the spine and result in disc damage and nerve compression with time.

Symptoms of Sciatica Pain

Mentioned below are the common symptoms of sciatica pain:

●  Burning sensation on the affected side
●  Tingling or “pins and needles” (paresthesia)
●  Numbness
●  Muscle weakness
●  Urinary incontinence
●  Fecal incontinence
●  Lower back pain
●  Hip pain

Diagnosis of Sciatica Pain

Early diagnosis of sciatica pain can be immensely helpful in choosing the best treatment. Here are the common diagnostic methods used by doctors: 

• Physical Examination: The physician will test your reflexes, muscle power, and joint movement. They will ask you to do certain movements, such as walking on the heels or toes, to detect the location of pain and the involvement of nerves.
• Imaging Tests: If the pain is severe or associated with muscle weakness, imaging tests are performed to search for structural problems.
• X-ray: The doctor may perform an X-ray to detect bone spurs and spinal alignment.
• Computed Tomography (CT) Scan: Using this, doctors check your spinal cord and nerves through sharp, cross-sectional pictures of the spine. 
• Magnetic Resonance Imaging (MRI): This procedure provides precise images of soft tissues such as discs, nerves, and the spinal cord to identify herniated discs or other pathology.
• Electromyography (EMG): This examination tests the rate at which nerve impulses travel along muscles. It assists in identifying whether a herniated disc is putting pressure on nerves that regulate muscle function.
• Additional Imaging: If the initial examinations are unrevealing, further imaging such as a myelogram (contrast dye and X-ray/CT scan) can be suggested to better visualize the structures of the spine.

Medications to Get Relief from Sciatica Pain

There are several medications that can be used to manage sciatica pain. These include:

• Over-the-counter (OTC) medications such as acetaminophen, aspirin, or NSAIDs (such as ibuprofen [Advil, Motrin], ketoprofen, or naproxen (Aleve)
• Prescription muscle relaxants to decrease muscle spasms
• Antidepressants for chronic lower back pain
• Prescription opioids for more severe pain
• In advanced cases, a steroid injection can be given near the spinal nerve to relieve sciatica pain.

Sciatica pain may be debilitating, and leaving it untreated can lead to long-term complications. This is why early medical intervention is necessary. As no one can predict a medical emergency, availing of comprehensive health coverage makes sense.

Prevention of Sciatica Pain

The following are some of the preventive measures for Sciatica pain.

Stay Active with a Focus on Core Strength and Flexibility. Regular exercise is a highly effective way to prevent sciatica. Activities that strengthen the core muscles (abdominals and back) and improve flexibility in the hamstrings and hips are particularly beneficial for supporting the spine and reducing nerve irritation. However, if you do not observe any improvement or if the symptoms worsen with exercise, talk to your healthcare professional. 

Avoid Heavy Weights. Use lighter weights for strength training. If you are lifting heavy weights, ask for help from the trainer or another person.

Practice Good Posture. Following good posture techniques helps you release stress in the body, and tight muscles improve the performance of the lower body. That’s why it is recommended that while you’re sitting, standing, and sleeping, you maintain good posture. Wrong posture for a longer period can increase the risk of developing sciatica.

Keep a check on your body and maintain a weight that’s good for you. You can consult a dietitian to know about how much weight is healthier for you according to your age and height. You can also get guidance on what you should add and avoid to stay healthy.

Avoid smoking. It is a known fact that smoking affects your overall health. It reduces the oxygen levels your tissues receive. The discs present in the spine don't have a good amount of oxygen supply to start with; therefore, smoking can increase the risk of disc degeneration and damage that can lead to sciatica.
