The symptoms of subarachnoid hemorrhage are sudden cerebral vascular rupture, severe headache, nausea, vomiting and other symptoms. The blood in the blood vessels flows to the subarachnoid space to form subarachnoid hemorrhage. Secondly, patients with subarachnoid hemorrhage may also have unilateral limb hemiplegia. Early symptoms may be meningeal irritation, such as neck resistance. Other patients with severe illness may have symptoms such as coma due to intracranial brain tissue edema.
