We can easily get frostbite in winter because of the cold weather, and I’ve had frostbite too, and it’s really too uncomfortable, especially at night when I sleep and my feet itch too much. But itchy is itchy, and it doesn’t cause much harm to our lives. However, this is not the case for diabetic patients, as it is very likely to develop into a serious diabetic foot. A recent patient from Liaoning is currently undergoing referral procedures for an infection caused by frostbite. Let’s start with a brief understanding of the causes of frostbite. Usually, when the skin is cold, wet, or in a sudden change from cold to warm, the small local arteries contract, and over time the arteries become paralyzed and dilated, the veins become stagnant, and local circulation becomes poor. Whenever the temperature is high enough, frostbite will be particularly itchy, and at this time we will rub or scratch with our feet, which will inevitably result in wounds. Of course, we cannot rule out the possibility that severe frostbite will ulcerate on its own and form a wound. As we all know, diabetic wounds are difficult to heal and are a bit difficult to care for in winter, and sometimes they are difficult to detect and become infected. When this is combined with the poor local blood supply to the frostbite, the infection will worsen if the wound is not properly treated, and will then develop into a serious diabetic foot ulcer. Many patients consider this to be frostbite, so people are used to buying frostbite cream to use, and continue to apply it even after a day of failure, delaying the best time for treatment. I advise you never to do this, no matter what the cause of the wound, for diabetic patients are very dangerous, improper care and treatment can become diabetic foot let patients therefore amputation are possible. For the treatment of the already infected formation, the idea of treatment is the same as most of the slow trauma, the patient’s overall health should be noted to improve, control blood sugar (also adjust blood pressure and lipids), improve cardiovascular, and so on. Then for frostbite infected wounds, clean the wound, find a professional doctor to clean the wound, clean up the necrotic tissue, and then recommend the use of Chinese ointment with the effect of eliminating decay and regenerating the wound, correct the local metabolism, it can improve the immunity and proliferation of cells, then the speed of wound healing will be accelerated. In short, whether it is frostbite or other injuries caused by wound infection, it is necessary to do targeted treatment for local wounds, if this is ignored, treatment is often futile, and will be already serious wounds added to the pain of the patient.
