My 75 year old step father has recently been diagnosed with a enlarged prostate which cause acute urinary blockage. After 3 trips to the ER, he is still experience dizziness and hot flashes, mainly in his face and neck. After the last trip, 5 days ago, the tests showed that the resulting bladder infection is nearly gone, but the spells continue. Tests of his heart functions came back good. His son is now convinced he is having TIA s and wants him to go back to the ER again! Could there be a simpler explanation for these spells? Cheryl brown
