I have one sore boob, its mainly around the nipple area although I am getting shooting pains, not all the time but worse in the evening when ds cluster feeds. I noticed a yellowish s pot (tiny) on the nipple. Looks like it might be a tiny blister. I don't feel unwell. Any advice please. I am still feeding from that breast which is painful when I start to feed but gets better then pain comes back later in the evening ? ? What do you think it is and how can I make it better ? Thanks
