lumpy breasts

Does anyone have super lumpy breasts while bf? I've had fibercystic breasts before pregnancy but the Ropey lumpy areas never went down with periods Like most women's do. My breasts are so lumpy esp one more than other- feels so hard Ropey and lumpy. I got an ultrasound and it said normal lactating changes but a few months have gone by and the lumps are still there and I know I was told I have cysts but it feels so scary and I worry all the time. I'm wondering if this is common with women? Right now on top of feeling lumpy I feel a large hardened area above the nipple with cysts inside, cysts on the side of breast and now I feel a bean shape soft lump below the armpit. I'm having another ultrasound but this gives me anxiety. Is anyone else experiencing anything similar ?
