Flushing: You are describing facial flushing, which can occur for many reasons. It can be due to certain medications and supplements (such as niacin) or physical causes including a sudden increase in blood pressure. There are hormonal and other causes also. See your pcp who can obtain a thorough history including any associated symptoms, which may help identify the nature of the problem.
