Copper-colored or brownish spots on the tops of your feet and ankles are often a sign of hemosiderin staining, which is caused by the breakdown of red blood cells and the subsequent deposition of iron-rich hemosiderin in the skin. This discoloration can be associated with venous insufficiency, where blood flow in the veins, especially in the legs, is impaired.
Here's a more detailed explanation:
Hemosiderin Staining:
When red blood cells break down, they release hemoglobin, which contains iron. This iron can be deposited in the skin as hemosiderin, causing a reddish-brown or copper-colored stain.
Venous Insufficiency:
This condition occurs when the valves in your veins, which help push blood back to the heart, are weakened or damaged. This can lead to blood pooling in the lower legs and feet, increasing the likelihood of hemosiderin staining.
Other Causes:
While venous insufficiency is a common cause, other factors like trauma, edema (swelling), and certain medical conditions (like diabetes and cardiovascular disease) can also contribute to hemosiderin staining.
Symptoms:
Aside from the discoloration, you might also experience swelling, itching, or skin changes like dryness or scaling in the affected areas.
Treatment:
Treatment often focuses on managing the underlying condition, such as venous insufficiency, with measures like compression therapy, elevation of the legs, and medications to improve blood flow. In some cases, laser treatments or topical creams may be used to reduce the appearance of the stains.
When to see a doctor:
If you notice copper-colored spots on your feet and ankles, it's a good idea to consult with a doctor, especially if you have other symptoms like swelling or pain. They can properly diagnose the cause and recommend appropriate treatment.
Below: image. -This is my foot how it looked a year ago (July 2025) and how it looks today (July, 2026.) The left-image is a little color-incorrect (my cellphone stats for taking photos was out of norms) but it is quite representative of how my feet/ankles looked a year ago as we were still getting titration of my meds figured out. And yes, those regmaglypt 'thumbprint' impressions are from compressing the fluid-retentive skin. A little more than a year ago, this 'thumbprinting' ability went all the way up to my knees!
The image on the right is quite accurate though.
I still get some edema in the lower legs/feet but the four medications that I am on, -for as much as I loathe each and every one, -seems to be working...
