What Are the Causes of an Ischemic Foot Ulcer?
The Cleveland Clinic states that ischemic foot ulcers are open sores that keep coming back or do not heal. The sores consist of craters in the skin that can be shallow, or so deep that they penetrate to the bone. Ischemic ulcers are caused by a lack of circulation. They usually occur on the heels, between the toes or on the tips of toes, or anywhere the bones may protrude and rub against sheets, socks or shoes. They can also occur in the toenail when the toenail cuts into the skin. There are several medical conditions that can precipitate the occurrence of ischemic ulcers. Treating them often requires treating the underlying medical conditions causing them.
