Pattern Overview

Blood Stasis is a common pattern in restless leg syndrome, characterized by vascular insufficiency, restless legs, sharp pain, and aggravation at night. The core pathogenesis is stagnation of blood in the leg collaterals, leading to reduced perfusion, ischemic neuropathy, and restless sensations.
