Dizziness, spinning and vomiting when lying down may be otoliths, also known clinically as benign positional vertigo. Patients mainly present with dizziness, nausea, vomiting, and rotating vision, while patients can experience deafness, tinnitus, and other discomforts, often associated with position rotation. If the patient has left-sided otoliths, the symptoms are often obvious when the head position is turned to the left. If the patient has otolithiasis on the right side, the symptoms will be apparent when the head is turned to the right. Treatment is primarily repositioning therapy, and the condition can occur at any age. In addition, it can also be seen in cervical spondylosis. Patients with cervical disc herniation can compress the vertebral artery when their head is turned, causing insufficient blood supply to the vertebral artery and resulting in dizziness, nausea, vomiting, and some patients can also experience spinning in the sky. In general, patients do not have deafness or tinnitus, but can also have nystagmus and ataxia.
