Sudden episodes of facial flushing or widespread skin redness occur when blood vessels near the skin surface widen, increasing blood flow. Common triggers include strong emotions, certain foods or drinks, temperature changes, exercise, or even some medications. When speaking with a healthcare professional, they will likely ask about when the flushing occurs, what seems to trigger it, how long it lasts, and if you experience other symptoms like sweating, warmth, or bumps. Keeping a diary of potential triggers and noting the circumstances of each episode can be very useful. Seek urgent care if flushing is accompanied by difficulty breathing, dizziness, chest pain, confusion, or signs of a severe allergic reaction, as these require immediate attention.
