I am having pain in both breast. I had a mammogram and it was normal. My doctor suggested vitamin e. What is this vitamin E not working?

Unclear ?? Did you say you have taken vitamin-e or not yet? If it has been tried and did not help, ask your gynecologist to give you a short course of hormones which can often relive this type of pain in the best which is quite common(called mastalgia).Alternatively, try taking tylenol, (acetaminophen) 2 tabs twice daily during the week before your menses are due, as that is the time mastalgia is at its worst..
