What Is Sciatica?

by Son PMR(Physical medicine & Rehabilitation ) & Chiropractic Clinic in Seoul

1. Definition of Sciatica

Sciatica refers to pain that radiates along the sciatic nerve, which runs from the lower back through the hips and buttocks and down each leg. It is commonly caused by compression or irritation of the sciatic nerve, often due to a herniated disc or spinal stenosis.
However, in many real-life clinical cases, sciatic nerve pain is more often associated with muscular tightness or spasms, rather than direct nerve compression.

2. Common Symptoms

  • Pain radiating from the lower back to the buttock, thigh, and calf

  • Numbness, tingling, or weakness in the leg

  • Difficulty walking or sitting for long periods

  • Pain worsening with coughing or sneezing

3. Causes

  • Herniated Disc: A bulging disc pressing on the sciatic nerve

  • Spinal Stenosis: Narrowing of the spinal canal causing nerve compression

  • Piriformis Syndrome: Tightness in the piriformis muscle in the buttock compresses the sciatic nerve

  • Spinal and Pelvic Misalignment: Imbalanced posture or muscle tension irritating the nerve

  • Upper Cervical Misalignment (C1–C2): Misalignment of the upper cervical vertebrae can affect the balance of the pelvis and lower spine, contributing to sciatic symptoms due to the close neurological relationship between the cervical spine and the sacrum.

4. Non-Surgical Treatment Options

  • Medications: Anti-inflammatory drugs (NSAIDs), muscle relaxants, and nerve pain relievers

  • Rehabilitation Exercises: Strengthening the lower back and core muscles

  • Nerve Block Injections: Reducing inflammation and pain around the irritated nerve

  • Chiropractic Care:

    • Upper Cervical Adjustments: Correcting misalignments in C1 and C2 to help restore nervous system balance

    • Lumbar and Pelvic Adjustments: Improving spinal alignment to relieve nerve pressure

5. Prevention & Management

  • Maintain good posture, avoiding slouching or twisting

  • Regularly strengthen core and lower back muscles

  • Use proper lifting techniques (bend at the knees, not the waist)

  • Stretch frequently if sitting for prolonged periods

6. Final Thoughts

Sciatica is not always caused by direct nerve compression. Often, muscle tension, pelvic imbalance, and even upper cervical misalignments play a key role in its development. For long-term relief, a whole-body approach is important.

 What is Central Sensitization? by Son PMR(Physical medicine & Rehabilitation ) & Chiropractic Clinic in Seoul Central sensitization refers to a condition where the brain and spinal cord become abnormally sensitive to pain signals following an injury or inflammation. In simpler terms, the pathways that perceive pain become overly reactive, causing individuals to experience excessive pain from minor stimuli or persistent pain even after healing . Key Features of Central Sensitization Amplified pain responses (Allodynia) Pain is felt even with non-painful stimuli, such as light touch or gentle movement. Increased pain sensitivity (Hyperalgesia) Painful stimuli feel much more intense than usual. Persistent pain Pain can continue even after the original injury or inflammation has resolved. How Central Sensitization Develops Peripheral nerve injury or inflammation → Continuous transmission of pain signals to the spinal cord and brain → Hyperexcitab...
