Facial blushing or flushing can have various causes, ranging in severity from 'minor' to 'life-threatening'. Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.
Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms. In order to diagnose facial blushing or flushing, we could:
|Caffeine Intoxication||2%||Ruled out|
|Carcinoid Cancer||1%||Ruled out|
Do you experience facial blushing, flushing or redness more frequently or intensely than would be considered normal? Do not count blushing during embarrassing situations.
Possible responses:→ Don't know / I think I'm average
→ No, definitely not
→ Mild / occasionally
→ Moderate / sometimes
→ Major / often
The facial flushing can be temporary or constant and usually appears suddenly on the face or neck. The flush looks deep red or purple. When this occurs, you may also feel warm, unpleasant, and have a rapid heartbeat. The flush may last only a few minutes in early stages of carcinoid syndrome and may last hours during later stages.
