(Note: Crane's Knee Wind)
This condition is also similar to Bi syndrome (Bi Syndrome, obstruction of meridians causing pain and numbness), commonly known in folklore as White Tiger Li Jie Feng. "White Tiger" refers to the severe pain feeling as if bitten by a tiger; "Li Jie" refers to the pain traversing sequentially through the joints of the four limbs.
It occurs because during summer, when the Cou Li (skin pores and interstitial spaces) are open, one indulges in cooling off and catches wind; or sits and lies on mud or lacquered surfaces, contracting wind-dampness; or exposes oneself to wind while sweating; or contracts wind after drunkenness. In autumn and winter, when the Cou Li are closed, pathogenic factors of wind-cold-dampness combine with Qi and Blood, leading to curling of fingers, swelling of legs and knees, and unbearable excruciating pain. There are also cases where pain is caused by the flow and deposition of damp-phlegm. If due to wind-cold, pain is worse at night; if due to damp-phlegm, pain persists equally day and night. A floating and large pulse indicates wind-cold; a wiry and thin pulse indicates dampness; a slippery pulse indicates phlegm. Treatment should employ acrid-warm methods to release the exterior and expel wind-cold-dampness pathogens, such as Danggui Niangong Tang (Angelica Root and Ligusticum Pain-Relieving Decoction).
If caused by damp-phlegm, use methods to leach out dampness and guide out phlegm; once pain subsides, concurrently nourish blood and relax sinews.
