I seem to have constant milk blisters in my left breast and my left nipple is always hard. As you can imagine the pain from the blister is bad and the hard nipple is Soo uncomfortable. Why does this keep happening ? Any suggestions ? What about the hard nipple ? What can I do. My breast is tender all the time and the initial latch is very painful but gets better with nursing? Any help?thx in advance for taking the time to answer.
