My mother has been dealing with bouts of cellulitis on and off for a few years now. She went a year without having it until yesterday when it came back worse than it has ever been. The rash starts on her left breast and spreads up her chest and it has reached her back and arm before. She also experiences nausea/vomiting, fever, chills, and extreme fatigue. She is on antibiotics (I forgot what it's called) that help, but her doctor is baffled as to what is causing it. She did have breast cancer around 7 years ago and she has a surgical scar from it near her armpit, but the rash seems to form around her nipple/areola and spreads from there. My main concern is that her body is building up a tolerance to the antibiotics and if it becomes more severe her body won't be able to fight off the infection. I guess I'm posting this to see if anyone has experienced cellulitis before and/or any knowledge on it that exceeds a basic google search. Help?
