Later, she noticed a swelling in her tongue, but a doctor could not find anything wrong. It finally got so bad that she was having trouble eating, so she want back to the doctor. He did some tests, found a lump on her tongue, and did surgery.
During the surgery, he cut open the lump and a live cockroach crawled out. It was determined that she got cockroach eggs in her tongue from the envelope that caused the cut and they incubated there.
