Had a mammogram and a scan done today due to my feeling discomfort which I mentioned in my post a month ago. Good news! Everything seems ok, though they could not tell me why I should feel pain sometimes, except maybe that the breast tissue is changing and putting pressure on the scar tissue from the op 17 years ago? Anyway, it has put my mind at rest. Thank you all you wonderful people who suggested that I have it checked out. Hope everything goes well for you too.
