Yes, moreso if you come to grief. You have BP readings similar to what lead a friend of mine to suffer a stroke. He had headaches before the stroke happened. Nose bleeds are in that danger list also if you read up on high BP symptoms. Not sure what your BSLs are like during your hypos but falls and brain damage are possible. Speak with your endo and get admitted. Waiting for blood tests results does not solve the immediate danger. Those who say your BP just goes down again are not the ones who will suffer. Ask them how sending you home prevents you having a stroke - and if that happens who do you blame ?? You mention your Dad so there is a family history of heart trouble also and high BPs and low BSLs will not help that. Please get admitted..
