Suggest Treatment For Mastitis And Cellulitis

Yes,I have Been to 2 Different emergency rooms and the first said That I had mastitis and cellulitis and put Me on Antibiotics. The Next One gave Me fluids and meds for inflammation and more antibiotics through IV and then change My antibiotics. Then sent Me Home with a referral to the Breast Center. I went to the breast Center and The doctor Thought that it may be mersa (staph) so She suggested a Ultrasound and then Send Me to the Surgeon to have it cut and drained. Only theres was no pus pockets or sign of infection. She then told Me to continue Taking My Antibiotics and come back Tomorrow if its not any better. Well It may have went down a little. But My breast is still swollen, red, Heated. Im am really scared that It may be Inflammatory Breast Cancer. Please Give Me some advise.
