Advice welcome here. I can feel some lumps close to my nipple on one breast. They're sore when I press on them and sore when I sleep on that side in bed- so much so I have to move. It feels like a large, hard mass, maybe about the size of a 50p?? Other breast feels totally normal. Is this a straight to the doctor situation or a watch and see? For context, I'm 47, still having periods (in fact I'm due one anytime now). Definitely not breastfeeding and haven't for a number of years.
