Clinical frostbite on the feet is often directly related to the cold, but the vast majority of patients with frostbite on the feet can often be completely cured without further flare-ups after increasing warmth and improving local blood circulation. For patients with recurrent frostbite, it is important to start not only with warmth, but also with medication. Patients with recurrent frostbite often have a strong relationship with their own poor health and poor local blood circulation, which is difficult to improve, and is more common in older people. For such patients, you can take Chinese herbal medicines and apply them for foot soaking and fumigation, which are more effective. You can also take oral vasodilator drugs, such as niacinamide, nifedipine and dipyridamole, which are often chosen.
