I am a 51 yr old female. I have low potassium and take potassium and potassium sparing BP medicine (Aldactone). The aldactone is not for HBP. Normal BP is around 110/70. Yesterday I had blood drawn for an insurance exam, about 4 vials. BP taken at that time was 110/64. That seemed really low to me. Felt fine all day, then this morning I was very dizzy for several hours about an hour after waking. Had BP taken again at Walgreens. Now its high 137/79. Just took it with a wrist cuff (which I now read is unreliable) and its 132/80, pulse rate of 89. I am extremely tired and just feel off. Should I be concerned, or just chalk it up to having blood drawn? I was feeling fine up to that point.
