[|Human|] I was diagnosed with high blood pressure last Oct. when I was extremely dizzy to the point of not being able to stand up, vomiting and nausea. Since then and once on medicine, I had side effect of dizziness that lasted 5 weeks. Two weeks I was okay after the 5 weeks of side effect and since November 2014, I am dizzy 24 hours a day with a different type of dizziness (more severe than the side effect dizziness) that I was unable to walk straight, etc. for 4 months...now it is milder but dizzy all the time for the exception of sitting. I have been tested and it is not vertigo or any vestibular disorder. YYYY@YYYY
[|AI|]  As you were diagnosed as hypertensive and all your vestibular battery tests are normal as said by Yugo for a MRI brain this dizziness can be because of some migratory thrombus which may have occluded any minor vessel in brain...though a feeling of associated nausea and vomiting are again pointing more toward any peripheral disorder (like labyrinthine or possible deniers disease right now I would suggest you to go form brain carotid artery Doppler(look for occlusion of main artery to brain)pure tone audiometryserum vitamin B12 Levels
