A 35-year-old man in Brazil went to the emergency room with a mysterious pain in his right heel that got worse when he walked. When doctors first looked at his foot, they couldn't see anything wrong. But a closer look at the heel revealed a single strand of hair seemingly attached to his foot. The man was diagnosed with cutaneous pili migrans, a rare condition in which a hair shaft or hair fragment becomes embedded in the skin's surface.A fallen strand of hair seems harmless but was causing an excruciating pain. The 0.4 inches (10 millimeters) was removed with the help of a tweezer, and the man immediately felt relief from the pain. Only about 26 cases of cutaneous pili migrans have been reported in the last 60 years. Credits: https://www.google.com/amp/s/www.livescience.com/amp/strangest-medical-cases-2019.html
