Sounds like you got it again I would call Dr office for what to do.

Repetitive episodic vertigo needs to be fully evaluated, as an explanation needs to be uncovered and treated. Amongst the potential issues include otolithic dysfunction in the inner ear and Meniere's disease. Likely next step is to see an otolaryngologist, and undergo audiological/ vestibular testing.
