I have had a rash, swelling, bruising on my right breast for about 2 months now. was put on antibiotics. still have the problems. what should i do?

Maybe something else: Antibiotics may help with bacterial infections, but your problem is not likely bacterial infection. It is difficult to know what it is without further details/examination. Since it has been two months, i advise getting it rechecked...Possible fungal infection (like the one in picture here)? Possible need for a biopsy? Either way, reconsult doc. Good luck.

See your Gyn: With a persistent rash, swelling and bruising despite "treatment" you must have a more thorough work up. This should include a clinical breast exam, mammogram and ultrasound as indicated by the exam, a akin and or breast biopsy, even an mri. This can be a problem of significance including cancer, so called inflammatory breast cancer. Please get checked sooner rather than later.
