Hi my father if the last few months has been experiencing dizzy spells that come along with a fowl smell that he cannot liken to anything . Today sitting on the drive in his car he completely forgotten where he had cone from and what he d been doing he was incredibly pale . He is 65 and had a pulluminary emblem in 1999 - which brought in 2 heart attacks . He has since been fine but they above symptoms are rather alarming and I wonder what he should do. He is on Warfron and has a filter in his lung to stop clots
