How these symptoms affect the patient depends on to which organs or body parts blood supply is inhibited. Typical symptoms of Flammer syndrome are cold hands or feet, 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.
When your body is configured in certain positions, if you “apply pressure to the nerves that supply your hands and fingers,” then it's not unusual to experience the pricking, tingling ...
Most pressure-induced paraesthesia results from awkward posture, such as engaging in cross-legged sitting for prolonged periods of time. [2] Reactive hyperaemia, which occurs when blood flow is restored after a period of ischemia, may be accompanied by paresthesia, e.g. when patients with Raynaud's disease rewarm after a cold episode.

Ulnar neuropathy at the cubital tunnel is diagnosed based on characteristic symptoms and signs. Intermittent or static numbness in the small finger and ulnar half of the ring finger, weakness or atrophy of the first dorsal interosseous, positive Tinel sign over the ulnar nerve proximal to the cubital tunnel, and positive elbow flexion test (elicitation of paresthesia in the small and ring ...
Initially raised blood pressure followed by lowered blood pressure as the condition progresses. [52] Severe hypoxia can cause loss of consciousness, seizures or convulsions, coma and eventually death. Breathing rate may slow down and become shallow and the pupils may not respond to light. [52] Tingling in fingers and toes [53] Numbness [53]
Peripheral neuropathy may be classified according to the number and distribution of nerves affected (mononeuropathy, mononeuritis multiplex, or polyneuropathy), the type of nerve fiber predominantly affected (motor, sensory, autonomic), or the process affecting the nerves; e.g., inflammation (), compression (compression neuropathy), chemotherapy (chemotherapy-induced peripheral neuropathy).
A diagnosis should at a minimum include measurements of blood pressure and heart rate while lying flat and after at least three minutes of standing. The best way to make a diagnosis includes a range of testing, notably an autonomic reflex screen, tilt table test , and testing of the sudomotor response ( ESC , QSART or thermoregulatory sweat test).
Initial orthostatic hypotension is frequently characterized by a systolic blood pressure decrease of ≥40 mmHg or diastolic blood pressure decrease of ≥20 mmHg within 15 seconds of standing. [32] Blood pressure then spontaneously and rapidly returns to normal, so the period of hypotension and symptoms is short (<30 s). [32]
