My friend whom is 19 had mild chest pains in the area of the breast bone after having flu like symtoms. she flew to australia and was there for three weeks for the first week she was there she found she couldnt eat anything as the pain was quite bad and if she did eat she was sick when she returned to the uk the pains were still there and she was still struggling to cope with it.  She then went to the hospital who checked her heart and they told her she was fine that night she threw up clots of blood and what looked like pints of blood she was taken to hospital where she was sick blood again she now has low blood pressure and they cant take her blood as they cant find her veins they still dont know whats wrong with her yet they want to send her home!!!
