How these symptoms affect the patient depends on which organ's or body part's blood supply is inhibited. Typical symptoms of Flammer syndrome are cold hands or feet, a low blood pressure, occasional white and red patches on the face or neck, and migraine-like pain or a feeling of pressure behind the upper eyelid. In addition, there are symptoms not directly resulting from dysregulations of the blood supply such as a prolonged time needed to fall asleep,[2] a reduced feeling of thirst, high sensitivity not only to cold but also to odors, vibrations, psychological stress or certain medications (e.g., calcium antagonists, beta blockers) etc.
