Walking in high heels for long periods of time can cause the foot to suffer from very long periods of compression due to the characteristics of high heels. This leads to restricted blood circulation in the foot, blocked venous return and blood pooling, resulting in edema and congestion in the tissue spaces and swelling of the foot. In this case, the foot should be released from compression, including the removal of shoes and socks. It is best to lie down on a bed for rest and use a quilt or soft cushion to elevate the lower limbs, which must be higher than the heart, to facilitate blood circulation in the foot and promote venous reflux. You can also use warm water to soak your feet to promote blood circulation in the feet and help reduce swelling. Massage of the lower limbs, including foot massage, calf massage and thigh massage, can effectively promote venous blood flow in the lower limbs and reduce swelling, and physical therapy and hot compresses can also be used. After the above rest and treatment, the swelling can be dissipated within a short period of time due to the restriction of blood circulation in the foot caused by the compression of shoes.
