You recently recommended a special device called a Nipplette to a teenager whose nipple had always been turned inwards. Would the same thing work for me? I am 41 and my left nipple has suddenly become in-turned.

Any adult woman whose nipple becomes turned inwards must see a doctor immediately. This is one of those "danger signs" all females should know about because it may indicate cancer. Your GP will refer you urgently to the local Breast Unit, where I hope you will be seen within a week or so. Good luck.
