DOCTORS have been left mystified after a 20-year-old woman in Chile started crying blood.
Yaritza Oliva developed the condition earlier this month, and now bleeds from her eyes several times a day.
Miss Oliva, who lives in Purranque, Chile, said that the pain is 'indescribable', The Sun reported.
When she visited the doctor no infection was found so she was sent home with eye drops.
But, her parents, who cannot afford to send her to an appropriate medical expert, have asked friends and neighbours to help them raise funds for her.
Father, Jose, made an appeal on a local news programme.
The carpenter said: 'Please put your hands over your hearts, see our situation and help my daughter.'
Some experts have suggested that Miss Oliva has a condition called haemolacria.
The rare condition causes sufferers to cry tears of blood.
Haemolacria can indicate a more serious illness, such as a tumour and can be caused by high levels of hormones in women.
A teenage boy was diagnosed with haemolacria in 2009 after he cried blood three times a day.
Calvino Inman, 15, from Tennessee, said that he had no warning when the tears were about to occur.
He said that sometimes he could not feel them, and others it was like a burning sensation.
He and his mother appeared on television to appeal for help, but they did not find a cure.
Very little is known of the condition.
