Discolored Skin / Rash
Discoloration skin on legs at the ankle, calf, foot, or toes may be due to a venous insufficiency also called chronic venous hypertension. It starts as a subtle, fine red rash on the skin of the lower calf or ankle. With time, this rash becomes more obvious and covers a larger area of the ankle, calf, and/or foot. Eventually, the skin develops a brown.
Untreated venous or arterial conditions of the legs may lead to chronic venous stasis ulcers. These are the hardtop heal ulcers that tend to linger for years around the ankle and the lower leg. See a physician experienced in evaluation of abnormalities of the skin.
