My wife had been having extreme stomach pain for months, multiple trips to the emergency room, gastroenterologist, nothing could be found. She described that she felt that there was a hole in her stomach, the doctors called it stress.
On her final ER visit (two months after the pain began), something showed up in the CT scan (the 3rd one). Embedded in her belly fat was a wire. Everything clicked and I realized we had had steak on the grill the day that the problems started. She went into surgery and had the grill brush wire removed.
The wire had poked a hole in her stomach, and somehow worked its way out through the abdominal muscles into her belly fat. We are grateful that it exited that way, instead of into another major organ.
Beware.
