How does a venous leg ulcer form?
A leg ulcer prompts a cost question quickly, because open wounds seem urgent. This page explains how one forms and leaves price to the provider.
Pooled blood damages skin
my.clevelandclinic.org states: "Venous ulcers occur when oxygen-poor blood can’t flow from your extremities back to your heart." The same source continues: "Instead, it pools, creating pressure in your veins." Then: "This damages skin tissue and leads to an ulcer."
Where the cause sits
The sequence in that source is blood that cannot return, pooling, pressure, then skin damage. Related reading includes an encyclopedia entry on stasis dermatitis and ulcers, an encyclopedia entry on venous insufficiency, a clinic page on venous disease, and a clinic page on chronic venous insufficiency.
The question that makes a quote firm
This guide has no published rate source for treating an ulcer, so it gives no figure. A reader in Des Plaines should ask a provider what the quote covers: the wound, the underlying vein problem, or both. A quote that names only one is a ballpark for the whole problem.
A calm note
This page explains a mechanism from one public source. It cannot tell you why your skin broke down or what it will cost to treat.
