Your situation is similar to mine. My finger is swollen in winter. But it is easy to get angry at ordinary times. Before, I thought I was a hot constitution, but Chinese medicine said that I was deficient in qi and blood and had serious yang deficiency. Later, when I was engaged in health preservation, I realized that in the five elements of Chinese medicine, the pattern of the human body should be fire and water, and water should be fire. Now that our bodies are on the water, if the yang fire can't be hidden, it is easy to get angry, and the fire in the body will be lost because it can't be hidden, resulting in this state of the body. Pay attention to the combination of work and rest at ordinary times. You get up when it starts, and you sleep when it starts. In other words, you should go to bed early and get up early, and you must go to bed before 1 1, otherwise your face will turn blue and your blood will dry up when you get up the next day. Diet must be careful not to eat cold food, although the body is easy to get angry, but to eat something mild, such as ginger, jujube. Eat more foods that are beneficial to liver and kidney, such as black rice, black beans, black sesame seeds and black fungus. Drink less tea, especially green tea, and do not eat white radish. It's good for you to eat light diet porridge for invigorating the spleen and nourishing the stomach, because the spleen governs blood, while the liver produces blood and hides blood. If my fingers are frostbitten, I'll cook soup with Jiang Ye from Kobayashi. The swelling goes down every day and disappears the next day, so it can be reused. You can heat and soak it every day and then change it.
