I am male and my age is 32. During the past 10 years, the color of the skin of the upper side of my feet has become slowly darker. As you can see in the first photo, it is now almost brown. A dark mark has also developed gradually during the past 2-3 years under the fourth toe of my left foot, as shown in the second photo. On both cases, there is no pain, bleeding, swelling, itching or flaking off.
What could these indicate?
I would appreciate your answer! Thank you in advance!
This pooling of blood under the skin causes deposition of red blood cells. The red blood cells break apart under the skin causing brown or red pigmentation in your ankles, feet and lower legs. The pigmentation does not go away but fades to a brown colour.
