A girl who is unable to leave her home because blood can start spontaneously seeping from her eye, ears, beneath her tongue and from her scalp at any moment.
For 17-year-old Marnie-Rae Harvey, this horrific scenario is her everyday life.
Her mother is terrified for her daughter and says she has to “shake her every morning to check she is alive”.
Baffled doctors have no idea what is causing the bleeding, which is steadily getting worse, and have dubbed her the “Mystery Girl” as they struggle to come up with a diagnosis.
Until they do, the teenager is forced to stay at home as the bleeding could start at any time, and must cope with the stigma of her condition which means she has lost most of her friends.
Her mother said: “Every morning I have to shake her to see if she is still alive. It’s absolutely devastating. It happens every single day. We’ve just gone through 12 days of solid bleeding from her tongue and scalp. She is sick four or five times a day, vomiting blood.”
Last July, the teenager woke up with blood seeping out of her eye. She was rushed to hospital by her terrified family, but doctors could do nothing.Soon after, blood started seeping from her ears and from under her fingernails.
In the last couple of months the mysterious bleeding has spread to her scalp and under her tongue.
Cath said that her daughter had been coughing up blood and suffering from excruciating migraines for a couple of years before the bleeding started, meaning she was often to ill to go to school.
“It feels like we are living in a horror movie.
“At first it was only her eye. She woke up in a pool of blood. She came downstairs with the blood pouring from her eye. We rushed her to A&E but they could do nothing for her.
“Then it started coming from inside her ears, big blood clots, and then from under her fingernails. Recently, she tipped her head upside down and blood started spurting out from her scalp.
“The strangest thing is that her eye can be pouring blood until her face is covered and then suddenly it stops and the whites of her eyes are clear.
Cath said she feels frustrated that doctors are unable to diagnose her daughter’s condition.
“We’ve had it confirmed that Marnie does not have a brain tumour.
“Her blood tests come back clear and healthy, her iron levels are strong.
“She has no tumours, no blood diseases and no blood clotting disorders. Her blood clots well. Doctors have no answers, they are shocked. My local GP calls her the Mystery Girl. He knows what it isn’t but not what it is.”
An ultrasound scan showed her liver, kidneys, womb and ovaries and confirmed all organs are functioning perfectly, she added, and her eyes, ears, nose and throat are all fine.
