My friend in an other country is desperately ill. Docters thought ecoli infection was found in bowels,but were not sure, then the infection moved to kidneys, then heart, heart pulpitation and dropping vital signs and headaches began to occur, hot head - ice cold feet and lungs on fire within 3 weeks. She had dental work done this year ( 2 rootcanal ) and was wondering if that could be a factor of bacteria in blood...She went into hospital now this past sunday,where they gave her injections against blood clods ,but fear she is bleeding now from her brains, she is in a lot of pain and has been vomitting for these past 2 hours, what could cause all this docter Sjailja?
