Dizziness, nausea, and pain in the back of the head are mostly considered to have a cervical spondylosis attack. Cervical spondylosis is easily induced when the head is bowed for a long time or when working in a sitting position for a long time. Pain at the back of the head occurs when the neck muscles are too tight or when there is strain on the neck muscles, leading to sterile inflammation. In addition, misalignment of the cervical joints may compress the vertebral artery or stimulate the sympathetic nerve, affecting the blood supply to the brain, resulting in dizziness and nausea. In addition, if life and work are recently stressful, mental overstrain and physical overwork, neurological disorders in the brain may occur and brain function activity may decrease, which may also lead to dizziness, nausea and pain in the back of the head. In addition, when the back of the head is hit or collides with a hard object, pain in the back of the head may occur, and in serious cases, it may lead to concussion, accompanied by dizziness, nausea, vomiting and other symptoms. If dizziness, nausea and pain in the back of the head persist, it is recommended to go to the local hospital in time to improve CT of the cervical spine, CT of the head, cerebral hemogram and other examinations to clarify the specific cause, and then targeted treatment.
