For a long time, peripheral vascular diseases such as thrombo-occlusive vasculitis, atherosclerosis-occlusive disease, diabetic foot, varicose veins lead to blisters, infections and ulcers in the lower limbs or feet and do not heal for a long time, which seriously affects patients’ life health and quality of life. Due to the lack of corresponding specialties and the lack of systematic and effective treatment, they often “get worse and worse” and finally have to undergo amputation surgery. Diabetic foot ulcers account for more than 80 percent of such diseases, patients because of unsatisfactory blood sugar adjustment and prolonged disease, peripheral blood vessels, especially the lower limb blood vessel wall thickening, lumen narrowing, resulting in insufficient peripheral blood supply, secondary peripheral neuritis, and finally a very small cause such as hot water foot washing, corns, foot fungus, nail fungus, wear blisters, etc., can lead to infection and rapid spread, often within a few days of the foot extensive ulceration, Often, within a few days, the feet are extensively ulcerated, the toes become black and gangrenous, and even combined with sepsis, toxemia and other serious infections, with a high rate of disability and death. At present, the number of diabetic patients accounts for 8-10% of the total population, so it is especially important to focus on prevention and enhance individual awareness of health care. When there is coldness, numbness, tingling and burning sensation in the lower extremities and feet, it is important to ask the specialist if there is a combination of poor blood circulation or peripheral neuritis. If the diagnosis is clear, wear loose shoes and socks to reduce frictional injuries, and do not treat foot disorders on your own, but take oral or sedative medication to improve symptoms under the guidance of a doctor. In case of breakage and ulceration, prompt hospitalization in a specialized hospital is required to unblock blood vessels, improve circulation and localize minimally invasive. Stable condition can be achieved as soon as possible to promote healing and avoid amputation.
