Cracks in the skin at the back and sides of the heel are ugly and could be painful. They are reasonably common, particularly in those who are predisposed to them. These kinds of cracks in the skin around the heel happen when the skin is thicker and dry. As the fat bad underneath the heel bulges out sideways when walking puts strain on the skin that it may not take, so the skin just tears or splits. The using of open back sandals also plays a role in the condition. Various medical problems might also lead to the dryness of the skin and a numerous biomechanical issues contribute to the thickening of the skin.
After a crack happens, it does have to be treated as it could act as a portal to have an infection to get in. Firstly, an antiseptic needs to be used to prevent that if the crack is open. It is next necessary to take off the thick callus about the edges of the heel. This can be undertaken by a skilled podiatrist for those who have access to podiatry. Otherwise, then you need to use something like a foot file, pumice stone or emery board and get to work on removing the thick skin. This will take a lots of work. When that thickened skin is reduced, then it is crucial that you use creams and emollients to help make the skin soft and adaptable so it doesn't have the inclination to split. Urea based ointments are generally much better for that. Once this initial condition is taken care of, then preventative measures should be put in place to continue with or else the problem will probably occur again. Regular use of a foot file or similar is advised to keep the thick skin down and frequent use of a urea based ointment is important to help make the skin resistant to cracking and prevent the dryness. Avoiding open back footwear is also suggested.
