Swelling of the feet is a very common symptom, and there are many causes of foot swelling. To quickly eliminate foot swelling, the cause needs to be clarified first. The most common cause of foot swelling is trauma. After trauma to the patient’s foot, soft tissue edema of the skin can occur, resulting in swelling of the foot. When this symptom occurs, ice packs can be applied locally for cold compresses in the early stages of trauma, which can reduce local inflammatory exudation and thus relieve edema. After 24 hours of trauma, you can apply hot compresses or Chinese herbal medicines to eliminate swelling and relieve pain. It is also necessary to properly elevate the affected limb. Proper elevation of the affected limb at night while the patient sleeps can avoid poor venous return and can reduce foot swelling. Edema of the feet, there may also be other diseases, such as patients suffering from chronic diseases such as cardiac insufficiency, renal failure, liver cirrhosis, etc., may also have swollen feet and need to be treated for the cause in order to eliminate the swelling of the feet.
