Having been diagnosed with a small AN 3 years ago (11mm) I was put on watch and wait after the first year it had grown to 12 mm second mri in feb this year was told by letter no significant growth. However over the past few months I am finding I can go slightly dizzy with my whole body feeling tingly and feel like I m struggling to keep awake !! Have nearly collapsed a few times !!Can happen whilst working or sat relaxing, have spoken to my GP, had bloods done heart rate blood pressure all comes back ok, question is has any one else suffered with this????
