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.

Can frostbite be cured completely?

Chilblains can recur because, in addition to cold being the primary cause, many other factors such as the skin's moisture, abnormalities in the microvasculature, autonomic dysfunction, malnutrition, anemia, and endocrine disorders might also contribute to the condition. Additionally, lack of exercise, excessive sweating of the hands and feet, overly tight shoes and socks, and prolonged outdoor work can also promote the occurrence of chilblains. Thus, chilblains are a multifactorial disease. The best way to prevent recurrence is through preventive measures. These include: first, strengthening physical exercise to promote peripheral circulation and enhance the body's ability to adapt to the cold; second, early in the early winter season, it is important to prevent cold, frostbite, and dampness, stay warm, and avoid wearing tight shoes and socks; third, once exposed to cold, one should not immediately warm up by a fire or soak in hot water; fourth, irradiating the affected areas with infrared before winter or frequently soaking feet in hot water can also help in preventing chilblains.

Does soaking feet in ginger treat frostbite?

Soaking your feet in ginger water can effectively help improve chilblains and also achieve therapeutic effects, so it can be done daily. It is still necessary to keep warm and avoid getting cold, because if the condition is too severe, simply soaking your feet can be relatively slow. Foot soaking can only play a temporary role, so more attention is needed usually. You can soak your feet daily, maintaining the water temperature around 40°C. Moreover, the soaking time should generally be controlled between 15 to 30 minutes to effectively help improve the condition. If the chilblains are severe, some medications can be applied for treatment. (The use of medications should be carried out under the guidance of a professional doctor.)

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 frostbite be soaked in hot water?

Chilblains should not be soaked in hot water. Chilblains are generally caused when a part of the body is exposed to low temperatures, causing the capillaries and other small blood vessels to constrict due to the cold. Therefore, suddenly soaking them in hot water can cause these already damaged capillaries to suddenly expand, leading to worsening of the chilblains, swelling, and even infection. If chilblains occur, it is essential to receive proper medical treatment.

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.
