I've had vertigo, dizziness, sudden falls in the middle of the room, hearing loss, and tinnitus for over 20 years. My diagnosis is Migraine Associated Vertigo. I also have fibromyalgia which can also affect the balance. Anyone have long-term dizziness, other vestibular or auditory symptoms from one-time injection of a beta blocker for a cardiac CT scan with contrast dye? Any preventatives or after treatments that helped? I have one next week and I'm a nervous wreck about the potential for long-term effects of the beta blocker. Thank you.
