instruction: hello doctor I am a 25 year old female my mi is I am a non smoker with no ongoing conditions like diabetes I am not breastfeeding and have never been pregnant I developed mastitis very suddenly about three weeks ago by that evening I was in a and with a lump the size of an egg in one breast I was prescribed codamol and 500 my flucloxacillin a day after the first course which was 10 days I saw the doctor again as the lump had reduced to the size of a large grape but was still painful I often had fevers and I felt unwell doctor put me on another seven day course of flucloxacillin and booked a breast cancer screening I just finished my second course and I am still in pain with lump still the size of a small grape and still feel ill and feel like I am getting worse again breast is back to being red and swollen my only option to see a medical professional before my breast screening is to wait for several hours at an urgent care clinic after work should I try and get more antibiotics if so should I insist on getting a different kind also please be honest I know there is a chance it could be ibn but as a young healthy childless woman is it actually likely that I should prepare for bad news or not
output: hello let me assure you that there are no cancers which come suddenly and settles with antibiotics one breast cancer which progresses over a few period is inflammatory carcinoma of the breast but it does not come in days and settle with antibiotics you have a breast abscess that settled with antibiotics and some times a part of it gets walled with fibrous tissue were antibiotics do not reach it is called antibioma I would suggest you take linezolid 600 my twice a day as there are chances of resistance to flucloxacillin
