The symptoms of hot flashes, also referred to as vasomotor symptoms, are characterized by a warm sensation that takes over the upper body — typically around the face, neck, and chest area. You may even feel as if your face and upper body are on fire or burning. This burning sensation may seem to come out of nowhere, spreading to other parts of the body depending upon how severe it is. You’re apt to feel flushed. You might then start to sweat. You may even get the chills.
