Meridian blockage refers to the blockage of the qi and blood running in the body. Symptoms vary depending on the cause, location and nature of the disease. Generally, it shows symptoms such as pain, unfavorable flexion and extension, hemiplegia (one side of the limbs can not move freely), slanting of the mouth and eyes, paralysis of the limbs, and so on. 1. Pain: If wind, cold and dampness invade the meridians and channels, qi and blood cannot move freely, causing pain in the limbs and joints, accompanied by numbness of the limbs, unfavorable flexion and extension, and heaviness and other symptoms. 2. Hemiplegia: if the deficiency of positive qi can’t move the blood, the veins and collaterals are stagnant, and the muscles and tendons are not nourished, hemiplegia, mouth and eyes slanting, paralysis of the limbs and other symptoms can occur. If the symptoms of meridian blockage occur, it is recommended to be treated under the guidance of a professional physician.
