in all probability what you're experiencing is simply irritation and dryness of the nipple which can be fixed by applying moisturizer. that said the full answer is a bit more complicated. the fact you're having pain throughout the whole breast presents something of a red flag. i'd suggest you see your primary care provider to have this more fully evaluated. obviously you don't want to take any chances that this is something more serious that just dry skin. even if you've had normal mammograms in the past tenderness in the breast is something to get evaluated. with luck it will turn out to be something simple but you'll get some peace of mind by having your health care provider evaluate this. good luck to you! regardless of your age clothes rubbing on your nipples can cause irritation. my wife was having the same problem. i suggested clear double sided tape. as crazy as it sounds it worked.
