Pattern Overview

Wind-Cold-Damp Bi is a common pattern in sciatica, characterized by cold pain in the leg, aggravated by cold weather, heavy sensation, numbness, and relief with warmth. The core pathogenesis is invasion of Wind-Cold-Damp pathogens into the leg meridians, causing obstruction of Qi and Blood flow, nerve root ischemia, and muscle spasm.

Key Symptoms and Differentiation Points

| Differentiation Dimension | Manifestations |

| :— | :— |

| Primary Symptoms | Cold pain in the leg, worse in cold/damp weather, heavy sensation, numbness |

| Associated Symptoms | Relief with warmth, stiffness, limited movement |

| Tongue and Pulse | Pale red tongue with thin white coating, floating and tense pulse |

| Pathogenesis | Wind-Cold-Damp pathogens obstructing the leg meridians |

| Etiology | Leg exposure to cold, autumn and winter seasons, living in damp environments |

Acupuncture Point Prescription

| Point | Location | Function |

| :— | :— | :— |

| BL23 Shenshu | Lower back, 1.5 cun lateral to L2 | Warms Kidney Yang, disperses Cold and eliminates Dampness |

| BL40 Weizhong | Midpoint of the popliteal crease (behind the knee) | Relaxes sinews and activates collaterals, benefits the lower back and knees |

| GB30 Huantiao | Midpoint between sacral hiatus and greater trochanter of femur | Master point for sciatica; on the Gallbladder meridian |

| Ashi points | Tender spots along the sciatic nerve pathway | Local pain relief and meridian unblocking |

Clinical Recommendation: Filiform needle, even method; moxibustion is strongly recommended to warm the meridians and disperse cold.

| Heavy sensation | Add Fang Ji, Yi Yi Ren to drain Dampness |

Western Mechanism Reference

Cold-induced radiculopathy with nerve root ischemia, muscle spasm, and reduced local blood flow. Wind-Cold-Damp Bi corresponds to sciatica exacerbated by cold exposure, where reduced blood flow to the nerve root and increased muscle tension contribute to symptom aggravation.
