The skin in the areola area of my left breast below my nipple has developed a puckered look and this is spreading to a bigger area. It also looks like the nipple is being pulled inwards and I can feel a large, hard, rough (it's definitely not smooth and doesn't move around) lump under the nipple area. Both of my breasts are pretty lumpy but this is definitely a different lump from how they usually feel and there is nothing like it in my right breast. Also, my left breast has become noticeably larger than my right one over the last couple of months. I have had to buy bras that are 2 cup sizes larger than normal to fit it in. I have an appointment to get it checked out later this week but am wondering what it could be.
