Hello Deanne Lienau
I have been going through your query.
Your symptoms of fever, with burning micturition, with raised leucocytes
in urine test are indicative of urine tract infection.
So you are absolutely right in considering you have a urinary tract
However one disturbing fact is the backache with passage of blood in urine.
Besides you have a structural alteration in renal pelvis
(3 separate kidney chambers or hoses).
All this really suggests a pyelonephritis
kind of features.
I would seriously advice you to get a urine culture and an ultrasound abdomen. They latter tells us if you really have pyelonephritis and the former tells us the kind of organism affecting you, with the most sensitive antibiotic.
Meanwhile you need to take plenty pf fluids.
Keep your sugars well under control.
You can start taking urine alkanisers.
Take some paracetamol
500mg as and when required for fever and bodyache.
Once the cultures are available, we can start on some antibiotics, specific to your case.
Best of luck.
