Why Caudal PDRN Injection Works for Persistent Leg Numbness

(Even when Nerve Blocks have failed)

By Dr. Son, Physiatrist & US-Licensed Chiropractor

 Are you struggling with persistent leg numbness or "pins and needles" despite receiving multiple nerve blocks? Many patients visiting Dr Son Rehabilitation Medicine & Chiropractic Clinic share this exact frustration.

If traditional steroid-based treatments haven't provided lasting relief, the answer may lie in Caudal PDRN (Polydeoxyribonucleotide) Therapy.

1. Moving Beyond "Blocking" to "Regeneration"

 Standard nerve blocks typically use steroids to suppress inflammation. While effective for acute pain, they often fail to address chronic tissue degeneration or nerve ischemia (poor blood flow).

  • The Power of PDRN: Extracted from salmon DNA, PDRN is a regenerative activator. It binds to Adenosine A2A receptors, which not only reduces chronic inflammation but also triggers the body’s internal repair system.

  • Angiogenesis (New Blood Vessel Growth): Leg numbness is often caused by a lack of oxygen to the nerves. PDRN promotes VEGF (Vascular Endothelial Growth Factor), creating new micro-vessels to nourish damaged nerves.

2. The Caudal Advantage: A Comprehensive Path

 Instead of targeting a single nerve root, the Caudal (Sacral Hiatus) approach allows the medication to flow upward through the epidural space.

  • Hydrodissection: The volume of the injection physically "washes out" inflammatory debris and gently separates internal adhesions (scar tissue) that are strangling the nerve.

  • Wider Coverage: This path ensures the PDRN reaches multiple spinal levels, making it ideal for patients with multi-level stenosis or complex disc issues.

3. Proven by Medical Evidence

 Our approach is grounded in clinical research. A notable study published in the journal Medicine (Baltimore, 2017) demonstrated that patients with lumbosacral radiculopathy—who couldn't take steroids due to conditions like diabetes—experienced a dramatic drop in pain scores (from 8/10 to 1/10) after epidural PDRN injections.

4. Why Choose Dr Son Rehabilitation Medicine & Chiropractic clinic?

 At our clinic, we don't just treat the symptom; we treat the person.

  • Safe for Everyone: Since PDRN is non-steroidal, it is a safe and excellent alternative for patients with high blood pressure or diabetes.

  • Holistic Balance: Based on my expertise in the CCMC (Cervical-Craniomandibular Complex), we evaluate your entire spinal alignment to ensure the numbness doesn't return.

 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...
