Cracks in the skin at the back and sides of the heel are unattractive and can be painful. They are fairly common, especially in those people who are susceptible to them. These kinds of cracks in the skin about the heel occur when the skin is thicker and dry. As the fat underneath the heel bulges out sideways when walking puts pressure on the skin that it may not take, so the skin just tears or cracks. The wearing of open back shoes also plays a part in the condition. Various medical disorders may also lead to the dryness of the skin and a numerous biomechanical problems contribute to the thickening of the skin.
When a crack happens, it does need to be taken care of as it can act as a portal for an infection to get in. First of all, an antiseptic ought to be used to avoid that if the crack is open. It is then necessary to remove the thick callus around the edges of the heel. This can be done by a competent podiatrist for those who have access to podiatry. If not, then you need to use something such as a foot file, pumice stone or emery board and get to work on removing it. This may take a lot of effort. As soon as that callused skin is removed, then it's crucial that you use creams and emollients to make the skin supple and adaptable so it doesn't have the tendency to crack. Urea based lotions are generally much better for that. Once this original condition is dealt with, then preventative approaches need to be put in place to continue with otherwise the condition will in all probability occur again. Occasional use of a foot file or similar is advised to keep the thick skin down and frequent use of a urea based cream is essential to help make the skin resilient to splitting and prevent the dryness. Avoiding open back footwear is also encouraged.
