Dizziness with spinning sensation when lying in bed, but relieved when sitting up, is typical of position-related vertigo. This disease is also called otolithic vestibular organ balance disorder. The specific site of the disease is in the inner ear, where there is a semicircular canal. When the hair cells in the semicircular canal shed and cause small masses, otoliths are formed. If it touches the balance receptors of the three semicircular canals, vertigo will be induced. However, when the position changes again, it is possible to leave the receptors again and the vertigo can be relieved, so it appears as a typical position-related vertigo. If it persists, it can be treated symptomatically with oral betahistine or difenidol, or with manual repositioning.
