The symptoms of diabetic foot can be categorized into those without wounds, commonly referred to as stage 0 diabetic foot. The main symptoms of stage 0 diabetic foot include lower limb paralysis, pain, intermittent claudication, severe lancinating pain, and other sensory abnormalities. This is what constitutes a stage 0 diabetic foot. Stages 1 to 5 of diabetic foot progressively involve wound ulceration, typically presenting as progressive ulceration, pain, and exudation. Therefore, it is recommended for diabetic foot patients to seek timely treatment from an endocrinology specialist, and to use medications under the guidance of a doctor to avoid worsening of diabetic foot infections and to prevent severe consequences.
