Pattern Overview
Blood Stasis is a common pattern in calf pain, characterized by sharp pain, deep vein issues or muscle strain, and aggravation at night. The core pathogenesis is stagnation of blood in the calf collaterals following injury or venous insufficiency, leading to pain and impaired circulation.
