Treated for cellulitis with bactrim, which helped. My question, could I have gotten cellulitus, the time my appendix ruptured? Dealt with the pain all night(didn t know it was my appendix), until my husband said I was going to ER! Got to ER, appendix is what was suspected, but when the MRI was done, they still weren t for sure. I was told by the surgeon that I was full of infection and, actually had gangrene! Stayed in hospital for t days, with IV and drainage bag. After this, is when I started developing the painful sores, boils, whatever. Thank you
