Pain is the most prominent symptom of blood stasis syndrome, because blood stasis blocks meridians. Blood stasis is a tangible evil, which hinders the movement of qi, so it hurts like acupuncture and the part is fixed. Because blood circulation is slow at night and blood stasis is aggravated, it hurts at night. If the blood stasis does not disperse or coagulate, it can form a lump, so the lump looks blue and feels hard.
Bleeding is due to blood stasis blocking collaterals and blocking the operation of qi and blood, which leads to blood rushing into collaterals and breaking, and overflowing without following meridians. Because the blood can't stop gathering, it is purple or has coagulated into a blood clot. Blood stasis, unfavorable circulation of qi and blood, and skin malnutrition will lead to dull complexion, misplaced nails, and blackened lips, tongue and nails. Obstruction of blood stasis, obstruction of chong and ren is amenorrhea. Filamentous red line, exposed blue veins and thin and astringent pulse are all manifestations of blood stasis and impassable blood vessels. The tongue is purple and dark, and the pulse is fine and astringent, which is a disease of blood stasis.
