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.)

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.

Can frostbite be soaked in hot water?

Chilblains occur when cold causes the small blood vessels at the extremities and peripheral ends of the human body to constrict and spasm, resulting in venous congestion and poor local blood circulation. Therefore, soaking the affected area in hot water can dilate blood vessels, improve microcirculation, and increase blood flow, which helps in treating chilblains. Adding some traditional Chinese medicinal herbs like safflower, Angelica sinensis, Salvia miltiorrhiza, dried ginger, and aconite to the hot water, which are known for their properties of warming and invigorating the circulation of blood and dispelling cold, can enhance the effectiveness of the treatment.

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.

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.
