A few weeks ago I found a lump close to my right nipple, at the same time I found another lump close to my left nipple. I went to the doctor about a week later who prescribed a 2 week course of antibiotics which I have just finished. I'm going back to the doctor later today as the antibiotics have not made any difference to the size of either lump. I am now very anxious and just wondered if anyone has had something similar?
