For the last two (or three - gasp) months, I've had a white lump on one of my nipples. It's a tiny bit smaller than this smilie but is white. When I put pressure around it, it whitens a bit more. If I'm in a warm shower, it tends to disappear a bit (the whiteness) and kinda disappears into the rest of my nipple but when I'm cold, it forms a distinct lump on the end of my nipple (well, a bit to the left of centre).

I haven't breastfed for about 5 months so am ruling out a mastitussy thing (plus I'm not sick). It can be itchy sometimes but I think that's just because I fuss with it and my nipples are a bit sensitive.

I've been meaning to ask my midwife but usually forget. I will try to remember again next week at my 31 week visit.

I'm not too worried, just wondering if anyone knows what it might be?
