Usually obvious: A warming sensation in the face, neck, and chest caused by lower estrogen levels.They are frequently visible to you and to others as a reddening or 'flushing' of the skin but, there are other medical causes of these sensations of feeling warm and, at the age of 36, you should see your healthcare provider if they persist. You are too young to be going through the menopause.
