If you get up when lying down with nothing to do, this is the occurrence of positional vertigo. Positional vertigo has the possibility of self-healing, or you can use forced postural exercise and long-term exercise in the evoked position, which can make the patient gradually adapt to it over time and no longer have vertigo. In addition, postural hypotension should also be ruled out. If the patient has sky-spinning vertigo, nausea and vomiting in severe cases, and the vertigo lasts for 3-5 minutes to be able to improve, it may be benign positional vertigo caused by otoliths, so you can go to the ENT department to do a position change test to induce vertigo and nystagmus, and do a reset to make the otoliths return to their original position.
