Hi, My mum (73) is on dialysis due to kidney failure, she is 5 foot 1 and weighs 69 kilos.  Last night she was poorly after coming off.  Her blood pressure was 175 when she left the unit at 7pm  and 210 later in the night ( 2hours later)she had a really bad headache and was sick quite a few times-   she refused to go to hospital .... Is this dangerous. what should I do if it happens again.  she seems better today
