I've had problems with dizziness for several years. At last I went to a neurologist and he suggested it may be V.M. and prescribed me propranolol. But I'm not sure about his diagnosis. I don't have any problems with my balance. My dizziness is more spaciness accompanied by difficulty thinking/concentrating, feeling pressure on my face and a feeling that I may fall asleep at any time. My headaches are also very mild.
My blood pressure is not high and propranolol can have withdrawal effects so I'm not sure about that either. If the goal is just to decrease blood pressure and improve blood flow, there are a ton of supplements that can do that such as citrulline, niacin, EGCG and many more.
