Twice in the last several weeks I have had a sudden, splotchy, red patch (looks similar to a hickey), that is also warm and itchy
, appear on my one breast. It's under the skin
and is not just a surface irritation, and has been at two different locations. It resolves itself within a day or two. I've recently had my yearly mammogram, followed by an ultrasound to check what turned out to be cysts, nothing of concern. I've not yet hit menopause.
