Getting up and lying down dizziness is related to the change of body position, mainly considering two reasons: first, consider otoliths, otoliths triggered by dizziness, there will be a significant reduction or aggravation due to the change of body position. So getting up and lying down with a particularly dizzy head is consistent with the symptoms of otolithiasis and requires a visit to an ENT doctor to identify whether it is otolithiasis. If it is an otolith, the dizziness can be reduced by resetting the otolith, and it is also necessary to apply nerve-nourishing and anti-dizziness medication, such as betahistine mesylate tablets. Second, consider the dizziness caused by bad cervical spine, after getting up and lying down, the dizziness will be more obvious with the action of bending the neck, so you need to take cervical spine X-ray or cervical spine CT to clarify the situation of cervical spine. If the cervical spine is bad, you can do acupuncture, massage treatment, and usually pay attention to the maintenance of the cervical spine to do more cervical spine exercises, do not work and study with the head down for a long time, dizziness serious can take strong dizziness tablets to stop dizziness.
