Dizziness and nausea when you turn over, dizziness as a sensation of rotating objects, feeling that you and your surroundings are rotating dramatically, and lasting for about a minute or a few seconds, and then the symptoms gradually disappear, followed by dizziness with nausea, is considered benign positional vertigo, also called otoliths. For this disorder, treatment of benign positional vertigo by manual repositioning is required in neurology or otorhinolaryngology. If the symptoms of vertigo, nausea and vomiting are more intense and cannot be combined with manual repositioning, you can take betahistine mesylate to control the vertigo symptoms and wait until the vertigo symptoms stabilize a little before repositioning. Benign positional vertigo is a self-limiting disease, which can gradually improve without treatment, but the symptoms may be more pronounced during the waiting process, and many people cannot tolerate it.
