Flammer syndrome is a described clinical entity comprising a complex of clinical features caused mainly by dysregulation of the blood supply. It was previously known as vascular dysregulation. [1] It can manifest in many symptoms, such as cold hands and feet, and is often associated with low blood pressure.

[2] Diagnosis is based on the symptoms after ruling out other possible causes. [3]
These together act to raise blood pressure back to baseline. [9] Apparently healthy individuals may experience minor symptoms ("lightheadedness", "greying-out") as they stand up if blood pressure is slow to respond to the stress of upright posture. If the blood pressure is not adequately maintained during standing, faints may develop. [3]
Alpha-blockers, like prazosin (Minipress®), are typically used to manage high blood pressure. These medications work by blocking the norepinephrine to help prevent blood vessels from tightening ...
