The heel is a weight-bearing part of the body, due to this feature, it will lead to chronic strain injury of the heel and various other factors, resulting in a series of symptoms. Itchy and painful heel, there are several common reasons: First, because the heel is in the weight-bearing parts, long-term weight-bearing will cause chronic strain on local tissues, resulting in poor blood circulation, blood stasis and thus produce nerve irritation symptoms. Nerve irritation symptoms will produce pain when heavy, and itchy symptoms when light, so the strain on the heel is the main reason for itching and pain. Second, because the heel is in the prominent part of the body surface, there is not a lot of local soft tissue or muscle protection, and it is easily stimulated by cold, damp and sudden changes in heat and cold, which leads to local nerve allergy and this itchy and painful feeling. Third, the patient has other underlying diseases, which can also lead to itching and pain in the heel. For example, diabetes, mostly accompanied by peripheral neuritis, can also lead to the nerves in the protruding parts of the limb being affected, which, together with long-term extrusion, can lead to itchy and painful symptoms.
