Calvino Inman, 17, has been suffering from the mysterious condition for two years and doctors remain clueless as to how to stem the flow of bleeding, which can last up to an hour at a time.
But a documentary which will be shown tomorrow night on American television explores the phenomenon, experienced by only a handful of people around the world.
He said: 'People still call me possessed. The bleeding happens all the time, at school, at home and in the night.
'I don't usually know when they're going to happen but sometimes it burns as it's coming out.
'Sometimes I don't even know it's happened until people start staring at me.
'But afterwards I feel like someone is hitting the left side of my head with a hammer.
'I can't sleep at night. I just lie there awake with the light out for hours.'
His anxious mother, Tammy Mynatt, said: 'We feel like the doctors have run out of ideas.
'We've been to see about 15 specialists from New York to Memphis to Atlanta. It's so frustrating to see my boy suffer like this.
The distraught 35-year-old is now appealing to overseas doctors to help. 'I just pray that someone out there knows how to help him,' she added.
The Boy With Bloody Tears, which appears on The Learning Channel (TLC), also features the bizarre case of a mum of three from Patna, India, whose tears of blood also leave her extremely weak and ill.
Rashida Begum, 27, began crying blood from her eyes three years ago, after a severe bout of vomiting and painful headaches.
Her doting husband Mohammed Aslam, 40, who married her against the wishes of his family, cares for her at their home, and helps look after their children Mohammed Adil, 10, Tehseen, eight, and five-year-old Asifa.
As Miss Begum's mystery illness intensified her husband was forced to quit his £5 a day job to care for his wife.
He said: 'I just want her to be OK, I want our kids to study, I want all this to go away and I want us to be normal again.
'We have tried everything, we have been to every doctor in Patna. We even spent 40 days praying at a shrine.
But the documentary offers new hope for Miss Begum as she is referred to experts at the All India Institute of Medical Sciences in New Delhi.
After numerous tests the doctors finally believe they have uncovered the mystery which links Miss Begum's strange bleeding to her painful and disabling stomach problem.
'I'm so grateful to the doctors for trying to help me,' she said. 'I cannot cope with the terrible bleeding any longer.'
Meanwhile, back in Tennessee Inman's doctor is exploring links to other unexplained bleeding cases in the U.S.
Dr John Fleming, of the Hamilton Eye Institute in Memphis, said: 'We usually find a reason for the bleeding, such as a growth or an infected tear duct.
'We have seen individuals who suffer from bleeding for months and years and then it suddenly stops.'
