Hi guys, can anyone tell me why i am getting such severe dizziness/imbalance when i stand up or stretch?? I have had my blood pressure checked recently and when i stand up it stays the same, even though im completely spinnin out :-( On one of the checks it actually increased but nurse said this was coz my heart rate increased coz i was worrying?? How can she be so sure?? I always hear of people getting dizzy when stading and its always to do with blood pressure dipping, but mine doesnt!! Ive had a normal heart ECG so im assuming its not that?? Im worried sick though! Does ne1 else get severe dizziness when standing up and stretching???? I almost fall over when i stretch!! Its so scary, please someone, put my mind at rest :-( Ive had a brain CT scan and ive not got tumours, it was all clear just one side of my brain looked complertely different to the other (aparently born like that!) Im thinking I need an MRI which shows more in-depth things like aneurysms/previous mini strokes etc etc.. I get bad palpitations all the time which give me huge adrenalin rushes throughout my body and head, my docs guna send me for a heart scan but its not until end of the month, im so terrifed im just guna collapse and die of SADS or something :( :( :( please help :( :( :( PS. as u can tell i am a huge worrier and do suffer from health-related anxiety..
