What is the reason for finger swelling? How should it be handled properly?

In winter, many people's hands, feet and ears are easy to freeze, causing chilblain to be painful and itchy, and some even fester and infect. In addition to the cold weather, there is another important factor closely related to blood circulation. In winter, people's activity is less, blood circulation and metabolism slow down, especially on the back of hands, ears and feet, which is easy to cause local tissue necrosis and chilblain. In order to prevent frostbite, besides keeping warm, the best way is to rub and massage your hands, feet and ears frequently, and insist on washing your face with cold water or proper physical activity to speed up blood flow. In the early stage of chilblain, two fresh peppers, two fresh eggplant roots, three fresh orange peels, eight slices of ginger and fifteen roses can be used. Stir-fry peppers, eggplant and ginger for fifteen minutes, then add roses and orange peel for eight minutes, and soak the juice on your hands and feet once a day. If it has festered, it can only be used after the wound has healed. Prevention and treatment of chilblain chilblain is the most common skin disease in winter, which mainly occurs in exposed parts of the body and limbs far away from the heart, such as ears, nose, hands and feet. ① Physical exercise: This is the best way to prevent frostbite, and improve the body's adaptability to cold through physical exercise. 2 preparation method for keeping out the cold: when working outdoors in winter, be sure to eat and wear warm clothes and make all kinds of preparations for keeping out the cold. For example, wear gloves, hats and cotton shoes. Keep the inside of clothes dry. Always rub some oil on ears, face, hands, feet and other parts that are easy to freeze to protect the skin. 3 cold and warm water method: In order to prevent frostbite, you can usually rub the easy-to-freeze parts with cold water until they are red, and wash the easy-to-freeze parts with warm water every night before going to bed. Can increase the cold resistance of these parts. ④ Single-headed garlic method: This method can be used for parts prone to frostbite every year before the arrival of winter. Take a garlic head, mash it, heat it in the sun, gently rub it on the frostbite-prone part until small bubbles appear locally, and then pick out the bubbles with a disinfection needle. This method can make local qi and blood unblocked, thus reducing the occurrence of chilblain. ⑤ Raw radish method; Cut the radish or green radish into large pieces (slices), put them on the fire, then gently rub the frostbite-prone parts, cool them and bake them again until the radish is completely hydrated. This method can prevent frostbite and treat frostbite. ⑥ Ginger (slice) method: Gently rub chilblain with a slice of ginger until it has fever, or use a slice of fresh ginger, simmer it by the stove, cut it into slices, and rub the affected area. Or mash 50 grams of ginger, soak it in Chinese liquor once or twice, mix well and apply it to the affected area three times a day. ⑦ Vinegar therapy: Take a proper amount of vinegar and heat it on the fire, then cancel the poisonous gauze and apply it to the affected area with vinegar. Prevention of frostbite: Wash your hands with cold water every morning and evening, and soak your fingers in cold water until you feel that you can stand the temperature of water. I usually soak for more than three minutes. Then dry your hands and apply hand cream. Water must be the kind that feels cold when put in. The principle of doing this is to adapt your hands to the cold feeling, promote blood circulation and increase your cold resistance. Frostbite will grow into small hard pimples at first, and it will itch in warm places, which is very sad. This method can also eliminate small hard bumps. Also, dry your hands in time after washing your hands and apply hand cream. Wet hands have poor resistance to cold air, because when water evaporates, it will take away the heat from their hands. Without hand cream, dry hands will itch and hurt in cold and dry winter. By the way, you must choose an absorbed hand cream. If you are not sure which is better, use baby lotion, which I often use. Never choose the one with high oil content, it will be so greasy that you don't want to apply it at all.
