hi everyone, i am new to the board but have a very important concern. my history is complex, but basically i have had cushings disease, and had pituitary surgery in 2000. since then i have had vertigo diagnosed as mav or migraine associated vertigo. ok, two times i was tested for hyperaldosteronism butfinally concluded i did not have it (with just one blood test) now i am scheduled for a bladder biopsy under general anesthesia tuesday. problem is i had to have a preop exam monday, which included a thallium stress test. since then, my bp has been 170/100 at times and then dropping to 90/50. my cardiologist has already signed off on the surgery but in the last five days i have not felt well one thing i have noticed is sleeping on my back causes a very low drop in bp and i have to turn to my side as it actually wakes me up. then around 2-4 in the afternoon my bp is up and i can tell simply by how i feel. the vertigo i have increases, i get a headache between my eyes and i get hungry. i know this is a lot in one post but my concern is should i go into surgery feeling like this. i have not had time to read many posts (reading the computer kicks up my vertigo) but if anyone can help me please, i would appreciate just your thoughts on what you would do. does this sound like hyperaldosteronism? what is my next step? thanks for your help...........judyv
