Petechiae (small red spots under the skin caused by bleeding)
Dr. Crilley describes petechiae as “like someone painted little red dots with a pen.” The spots, which you might not notice because of their size, painlessness, and placement in the lower extremities, indicate a low platelet count and are one of the symptoms of leukemia. According to Dr. Levis, petechiae are typically found around the ankles because gravity results in the accumulation of bodily fluids in the lower legs throughout the day.
