LOW BACK PAIN coming from nerves

 Radiculopathic low back pain is a pain that results from irritation or compression of a nerve root in the lumbar spine (lower back). This pain typically radiates along the path of the affected nerve. It is commonly associated with conditions like a herniated disc, spinal stenosis, or bone spurs that press on the nerves.

Key Features of Radiculopathic Low Back Pain:

• Pain location:
  • Low back: The pain usually starts in the lower back but often radiates to other areas.
  • Radiating pain: This radiating pain follows the path of the nerve affected by compression or irritation. Some of these nerves extend to the buttock area, the thigh or leg, or to the feet or toes. However, some of these nerves go to the hips, groin, or private areas.
  • Unilateral: It typically affects one side of the body, although it can also occur on both sides.
• Pain characteristics:
  • Sharp, shooting, or electric-like pain: Radiculopathic pain is often described as sharp, burning, or stabbing, with a sensation of electrical shocks shooting down the leg.
  • Numbness or tingling: Along with pain, individuals may experience numbness, tingling, or a pins-and-needles sensation in the areas served by the affected nerve.
  • Muscle weakness or spasm: Apart from unwillingness to move the legs due to pain, nerve irritation can also cause difficulty with walking, lifting the foot, or standing for extended periods.
  • Worsening with specific movements: The pain typically worsens with activities that increase pressure on the affected nerve, such as bending, twisting, prolonged sitting, coughing, or sneezing.
  • Relief in certain positions: Lying down or slightly reclining can relieve pressure on the nerve and reduce pain for some people.

Common Causes:

• Herniated disc: A disc between the vertebrae can rupture or bulge, pressing on a nearby nerve root.
• Spinal stenosis: Narrowing of the spinal canal or the spaces where nerves exit the spine can compress nerves, causing radiculopathic pain.
• Degenerative disc disease: Wear and tear on the intervertebral discs can lead to nerve compression over time.
• Bone spurs: Overgrowth of bone can develop in the spine, irritating or pinching the nerves.
• Spondylolisthesis: A condition where one vertebra slips forward over another, potentially compressing nerves.
• Infections or tumors: In rare cases, infections or tumors near the spine can cause nerve compression.

Diagnosis:

• Physical examination: Your doctor will assess your symptoms, test to see which part of the skin has an objective problem (something found in the doctor’s examination rather than your subjective complaint), and also look for abnormal muscle strength and reflexes. Your doctor will also perform maneuvers that may reproduce the pain.
• Imaging: MRI or CT scans are commonly used to visualize nerve compression and identify the underlying cause, such as a herniated disc.
• Electromyography (EMG): This test measures electrical activity in muscles to help confirm nerve root involvement.

Treatment:

• Conservative treatments:
  • Rest and activity modification: Avoid activities that worsen the pain.
  • Physical therapy: Strengthening and stretching exercises can help relieve pressure on the nerve and improve spine stability.
  • Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs), muscle relaxants, or nerve pain medications (e.g., gabapentin) can help manage pain.
  • Epidural steroid injections: Steroids injected near the affected nerve root can reduce inflammation and relieve pain. Read here for more information about epidural injections.
    
• Surgical options (if conservative treatment fails):
  • Microdiscectomy: In cases of a herniated disc, surgery may be performed to remove the portion of the disc pressing on the nerve.
  • Spinal cord stimulator: In some cases, the treatments mentioned above may not be effective. You continue to have pain, and you don’t want to consider surgery or have already had it with no good results. Here comes this treatment, which is fortunately one of the most effective available. It is like a pacemaker for your heart. It blocks the pain signal without affecting other normal feelings and functions. Read more about spinal cord stimulator here.
  • Laminectomy: In cases of spinal stenosis, this surgery involves removing part of the vertebra to widen the spinal canal and relieve nerve compression.

Do I need surgery for my low back pain?

Rarely will a doctor consider surgery just for pain relief in the absence of other factors. Surgery is done when everything else fails, there is something in your MRI that we are sure is the cause of your pain, you have other dangerous symptoms such as weakness, loss of muscle control, loss of control of bladder or bowel, or you feel numbness in your private area.
