Chilblains
Frostbite occurs on which parts of the body?
Chilblains are a cold-related disease, commonly occurring in the peripheral areas as a localized congestive inflammatory skin condition. They generally appear in the early winter or early spring when the temperatures are lower, which facilitates the onset of chilblains. The common sites for chilblains are the extremities and exposed areas, including the hands, face, and auricles.
What medicine is more effective for chilblains?
For the local treatment of chilblains, Western medicine generally uses some drugs to improve microcirculation. Commonly used drugs include compound heparin ointment, polysulfate mucopolysaccharide cream, vitamin E ointment, capsicum tincture, and so on. As for Chinese medicine, it is generally better to use some ointments that warm and drive out cold, activate blood circulation, and dissolve stasis. However, the most important thing for chilblains is to keep warm and prevent cold.
Is red, swollen, and itchy heel frostbite?
Let's talk about chilblains first, which can occur on various parts of the body. The most common cause is cold stimulation, such as redness and itching on the back of the heel, which may be due to occupational or other factors. The heel is often exposed and susceptible to cold, potentially leading to chilblains. This condition can be particularly troublesome but sometimes heals on its own as the weather warms up, though it is prone to recurrence. Treatment may require the use of vasodilators or traditional Chinese medicines that improve microcirculation and invigorate the blood. Regular physical exercise to boost immunity, avoiding cold exposure, and ensuring adequate warmth and dryness are important. Tight shoes and socks should be avoided, and it is not advisable to soak in hot water immediately after getting cold; instead, gradually increase the water temperature. If there is an open wound, appropriate ointments can be applied to promote healing, ensuring the area stays dry to prevent further chilblains. For example, soaking in water daily can be beneficial if there is no open wound, starting with water at 10°C, then increasing gradually to 20°C, and finally 30°C to gradually warm the area and improve blood circulation, aiding in recovery. Additionally, using ointments like chilblain cream can help improve the condition, but the area is still prone to reoccurrence if it gets cold again. Mainly, keeping the area warm and moist is crucial. For open wounds, regular disinfection with povidone-iodine and applying erythromycin ointment to prevent infection may be beneficial. (Please use medications under the guidance of a doctor to avoid inappropriate self-medication.)
Why does frostbite occur year after year?
Cold is the primary cause of chilblains, but in addition, factors such as the patient's own skin moisture, abnormalities in peripheral microvessels, autonomic nerve dysfunction, malnutrition, anemia, endocrine disorders, etc., may also participate in the development of the disease. Other factors such as lack of exercise, hyperhidrosis of the hands and feet, overly tight socks and shoes, and long-term outdoor work may also contribute to the occurrence of chilblains. Therefore, chilblains are actually a multifactorial disease, making it prone to recurrence.
How to remove the red marks left by frostbite?
For those with severe chilblains or prolonged exposure to cold, the affected tissue may suffer from hypoxia and cell damage, worsening the condition and potentially leading to blisters, erosion, and ulcers. Post-recovery, there may be residual pigmentation, such as red marks. Generally, the body undergoes a self-repair process where these marks gradually fade and disappear. For severe cases, applying ointments that improve microcirculation, repair the skin barrier, and reduce scarring can help accelerate the fading of these red marks.
Can ginger be used to rub on frostbite?
If the skin is not broken or ruptured after suffering from frostbite, ginger can be used to rub the affected area. However, the effectiveness of using ginger is not particularly good. But if the skin affected by frostbite is clearly broken or ruptured, ginger should not be used. Using ginger in such cases can cause severe irritation to the affected skin, which may likely lead to a secondary bacterial infection. It is recommended for patients suffering from frostbite to use some ointments that help improve local circulation.
Do chilblains hurt?
Frostbite occurs due to cold, causing the small arteries at the distal parts of our body to constrict, become paralyzed and spasm, leading to venous congestion and poor local blood circulation. Therefore, patients generally have symptoms such as itching and pain. Minor cases primarily present with itching which worsens with heat, while severe cases may mainly experience pain, especially when severe blisters, ulcerations, and further increased pain occur. If there is pain due to local frostbite, topical application of traditional Chinese medicine ointments that warm, expel cold, promote blood circulation, and relieve pain, or frostbite creams, capsicum tincture, etc., can be used.
Do chilblains itch?
Chilblains are caused by the spasm and paralysis of small peripheral blood vessels due to cold, resulting in venous congestion and poor local blood circulation. Sufferers generally feel pain and itching, primarily itching, which intensifies when heated. The best approach at this time is to apply topical medications, such as chilblain cream, capsicum tincture, etc., which have an anti-itching effect.
How to stop the itching from frostbite?
After suffering from frostbite, itching occurs mainly due to the stimulation of peripheral nerves causing an itchy sensation. Therefore, to relieve itching, one can apply some anti-itch creams such as frostbite cream. Saline, ginger, and soap can also be used to alleviate itching by promoting local skin blood circulation and constricting local blood vessels, thus having an anti-itch effect. After frostbite itches, one must not scratch, press, or touch cold water.
Frostbite is caused by how?
Chilblains is a condition many people have suffered from, especially prone to occur in winter. The main cause is due to poor cold resistance of the skin, coupled with low temperatures, which causes the peripheral skin blood vessels to constrict or spasm. This leads to local circulatory disturbances and tissue damage. Therefore, after developing chilblains, symptoms such as itching and pain are common, and it is essential to treat them promptly with medication.
