I was diagnosed with Mastitis 2 weeks ago. I was given Keflex. I had to go to the ER, due to being uninsured. I was told upon discharge to have a mammogram immediately upon completion of medication. That isnt possible, because as I stated, I have no insurance and cannot self pay. I finished the antibiotics, cold packs, warm compresses, ibuprofen for pain etc. The antibiotics did not work, not even a little bit. I am aware I should be having this rechecked, but I cannot. I cant afford another trip to the ER, unless its critical. My question is, what are certain symptoms I need to watch for, with this untreated infection, that may indicate serious trouble? Is there anything I should look for, that will warrant the expense of another ER visit??
