I had a mammogram (both breast) and ultrasound 4 months ago for a lump in my RIGHT breast. Everything came back normal. I have 2 fat globules on my right breast. A few days ago developed a red painful bump on my LEFT breast. I applied Mupircorin on it, thinking it might be another biol or small staph infection, which I've had in the past. The pain had gone away and so has the redness, but now I have a hard lump!!! I tried squeezing it to see if any discharge would come out and nothing. I am starting to freak out. After I squeezed it I noticed little dimples (like orange peels) which I know could be a sign of breast cancer. Can injure or sqeezing the skin hard cause this. Can an infection leave a hard lump. I am really starting to worry and I know I should bring this to my doctors attention. The only thing that is keeping me sane is the fact that it wasn't there a few weeks ago and I had fairly recent mammorgram done and an exam by my doctor. Any advice would be much appreciated.
