im 19 years old and i have had a lump on my nipple edge of my left breast for the last 4 weeks. at first it was painful so i went to my doctors who put me on antibiotics for an infected spot. the 'spot' has not cleared. this morining it went bright blue, but returned to its red clour an hour later. its hard to touch but not really that pain ful. i never finished my antibiotics but if it was an infection my own immune system would have fought it by now.
i have recently changed my diet to a more healthier one if that could be linked?
