Subarachnoid hemorrhage

A subarachnoid hemorrhage is the bursting of a blood vessel in the brain. This results in sudden bleeding into the space between the middle lining of the brain (arachnoid membrane) and the brain itself.

A subarachnoid hemorrhage causes sudden, severe head pain. This condition requires immediate medical care to prevent brain injury and death.
