question: Hello,In the past 10 months I have experienced 3 episodes of vertigo. The last one was 5 days ago and it was the worst. My doc has me on betahistine to control any dizzy spells. He thinks I may have a viral infection. I am terribly ill. I have headaches, shakes, nausea, am weak and just a general sense of feeling sick. Is this normal and how long should it last? I am terrified by the dizziness as I have 2 kids and can t live with this forever.
