Featured Viewer Question:
What would cause blood under the skin on the soles of feet?
Blood under the skin of the soles of the feet most commonly occurs because of
stress forces on the skin during walking or running, typically as a result of
improper footwear. It can also be caused by puncture wounds or trauma to
the foot. Rarely, bleeding disorders can lead to blood spontaneously
leaking into the skin under the foot. Occasionally, rupture of the
ganglion cysts from the knee can bleed through the tissues of the leg into the
bottom of the foot.
Thank you for your question.
