There are many reasons why patients continue to experience dizziness for several days: 1. Common causes in the elderly may be due to cerebral atherosclerosis, cerebral insufficiency of blood supply, or hypertension, hypotension, or cerebral ischemic lesions. If the patient has sudden inflexible limb movement, consider cerebral congestion or cerebral hemorrhage, which are serious diseases. 3. If the dizziness is accompanied by tinnitus and stuffy ears, it should be considered as peripheral vertigo disease, such as Meniere’s disease.
