Feet Can be Windows to Overall Health:

MD Podiatrist
While our eyes are believed to be the windows to our souls, could our feet be the windows to our overall health? “The foot is a complicated body part, but something we often take for granted,” said Daniel Michaels, DPM, a podiatrist at Banner Health Center. “While we usually don’t get concerned about our feet until we’ve bruised, sprained, or broken something, our feet can tell us a great deal about our overall health.”
Dr. Michaels has this sage advice: “Look, common things are common, and rare things are rare,” he said. “The likelihood is that you are perfectly fine. Most likely your symptoms are benign, but it is important to be aware of anything that could be an underlying health condition.”
