Acute lumbosacral radiculopathy with loss of sensation is a condition involving irritation or compression of one or more nerve roots in the lumbosacral spine (lower back and sacral region), leading to pain, numbness, or weakness radiating along the nerve’s pathway. Loss of sensation specifically indicates sensory nerve involvement, often due to conditions like a herniated disc, spinal stenosis, or trauma.

Key Points:

• Symptoms: Sharp or burning pain radiating from the lower back to the buttocks, legs, or feet (e.g., sciatica); numbness or tingling in the affected area; possible muscle weakness.
• Causes:
  • Herniated or bulging disc (most common).
  • Spinal stenosis or foraminal narrowing.
  • Trauma, infection, or inflammation.
  • Rarely, tumors or systemic conditions like diabetes.
• Diagnosis:
  • Clinical exam: Assessing sensation, reflexes, and muscle strength.
  • Imaging: MRI or CT to identify nerve compression.
  • Electromyography (EMG) or nerve conduction studies to confirm nerve involvement.
• Treatment:
  • Conservative (first-line):
    • Rest and activity modification.
    • Physical therapy to strengthen core and improve mobility.
    • Medications: NSAIDs, muscle relaxants, or neuropathic pain drugs (e.g., gabapentin).
    • Epidural steroid injections for severe pain.
  • Surgical: Considered if conservative measures fail or if there’s significant neurological deficit (e.g., discectomy, laminectomy).
  • Lifestyle: Weight management, posture correction, and avoiding aggravating activities.
• Prognosis: Varies; many improve with conservative treatment within weeks to months, but severe cases may require surgery or lead to chronic symptoms.
• Red Flags: Seek urgent care for loss of bladder/bowel control, progressive weakness, or severe pain, as these may indicate cauda equina syndrome, a medical emergency.

If you’re experiencing this, consult a healthcare provider (e.g., neurologist or orthopedic specialist) for a tailored plan.
