Pain can cause patients to experience dizziness and nausea. For example, when patients experience gastrointestinal colic the sympathetic nerves are stimulated, leading to nausea and vomiting. Patients are also prone to blood pressure fluctuations and vascular spasms in the presence of painful stimuli, leading to symptoms of dizziness. For example, in migrainous vertigo disorders, patients may experience headaches, leading to problems with dizziness and nausea. In particular, vertebrobasilar migraine is more likely to cause patients to have symptoms of dizziness and nausea, and may also have symptoms of inflexible limb movement or visual field deficits during attacks, all due to pain. There are many causes of pain, which should be clarified by combining the patient’s form of onset, specific location, and relevant examinations.
