Foot pain is a relatively common symptom in daily life. Generally speaking, depending on the cause of the foot pain, the department to which the patient goes to the hospital is different. 1. If the foot pain is caused by fracture or trauma or nerve compression, the patient needs to go to the orthopedic department of the hospital. If the foot pain is caused by gout, the patient needs to go to the endocrinology department of the hospital and improve the measurement of uric acid index to assess whether the patient needs to be treated with uric acid reduction. 3. If the foot pain is caused by vascular lesions, the patient needs to go to the vascular surgery department or general surgery department of the hospital and improve the vascular ultrasound examination to assess whether the vascular lesions are in the veins or in the nerves. The next treatment plan can be formulated by improving the vascular ultrasound examination and assessing whether the lesion occurs in a vein or an artery.
