Breast changes

Shayla

So I have swollen lymph nodes in my armpit it’s been a few months. I have been in for a mammogram and it was normal that was about a month ago. For a few months my breast have had a purple splotchy look today the splotches turned bright red. I am waiting to go to the doctor in a few days. My question is has anyone else had this or know what my doctor should be looking for they can find anything wrong? The pictures are not when it was full blown it is starting to go back to the purple.
