"If I still have it it's antibiotic resistant and needs stronger IV antibiotics"
Vicky, if you are suffering with a bacterial infection that requires hospitalisation, you are not too exhausted to get help. You feel like such absolute shit as your temperature rises and rigors and sepsis sets in, You will get seen quickly because the longer its left untreated, the higher the chance of permanent organ damage.
When you are that ill, you don't care about packing a bag, your brain is fried along with your body. Basic things like you might need to see a doctor take some working out. All you know is that you feel intolerably shit.
I'm still convinced she's talking about commensal E coli or an infection brought about by poor hygiene. If there's any infection at all.
Also, all bacteria have anti microbial resistance. That's how they survive and why Streptomycin was first isolated from soil, Everywhere there are bacteria, there are ways that they combat each other, survival of the fittest. The problem is that we have a limited number of antibiotics that target specific molecular pathways, and the genes providing resistance are often on plasmids, which are one of the main vehicles for horizontal gene transfer (i.e. bacteria can swap them with each other). I've ranted about this before in the munchie thread so will hold off.
Vicky, if you truly have a bacterial infection, follow the instructions to the letter. Don't let strains with different resistance profiles get a chance to proliferate, then its game over. You are not a candidate for an antibiotic of last resort and its not a nice way to die.
