I am a breastfeeding mom of a 7-month-old baby boy. In my 7 months of breastfeeding my baby, I went to the doctor twice because my breasts became tender and whenever breast milk comes out, my breast felt sore. The first time I went to the doctor, she gave me antibiotics and my breasts became normal. 2 weeks ago, I felt that my breast is painful again. I went to the doctor and gave me antibiotics again. And now, I feel it again. I can also feel some lumps and my right boob is painful again. Could this be mastitis or a more serious condition? Please help me. I'm panicking.
