Pattern Overview

Wind-Cold-Damp Bi is a common pattern in coccyx pain, characterized by cold-dampness type pain, heavy sensation, and aggravation in cold and damp weather. The core pathogenesis is invasion of Wind-Cold-Damp pathogens into the coccygeal region, causing obstruction of Qi and Blood flow and chronic pain.

Key Symptoms and Differentiation Points

| Differentiation Dimension | Manifestations |

| :— | :— |

| Primary Symptoms | Cold and heavy pain at the coccyx, worse in cold/damp weather |

| Associated Symptoms | Relief with warmth, heavy sensation, limited sitting tolerance |

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

| Pathogenesis | Wind-Cold-Damp pathogens obstructing the coccygeal collaterals |

| Etiology | Exposure to cold and damp, prolonged sitting on cold surfaces |

Acupuncture Point Prescription
