Chinese Man's Heart Holds 36mm Needle, Bladder Holds Sewing Needles

Chinese doctors found a 36mm sewing needle embedded in a 35-year-old man's heart, despite him having no heart-related symptoms. The man had been experiencing painful urination and blood in his urine, and CT scans revealed multiple metallic objects lodged in his body. Doctors removed the cardiac foreign body during surgery and found needles in the bladder. The patient recovered well, but the cause of the needles in his body remains unclear.
