What Causes Flank Pain,fever And Pus In Urine?

Hi, may I answer your health queries right now ? Please type your query here...Hi I've been sick since Febuary.
I think that I had Bacterial Vaginitis, turned into a
yeast infection, & then a UTI. I think I got
misdiagosed & have had a UTI since then.
I have a low-grade fever, pain on my right side
by where my urinary tract is, & sometimes dull pain
in my back by my kidney. I've been on Ciprofloxacin
500 mgs for 3 days, Cephalexin 250mg, Macrobid
100mg, Pyridium 100mg for pain, & now I'm on
Doxycycline. On Tues I was given that medcn,
& I recieved some kind of antibtc shot.
I am seeing my Dr in the Women's
Clinic tommorrow or next week to follow up from Urgent Care at
the VA in Temple, TX. I'm nervous and scared
about what is wrong in there & I need help figuring
it out. I've also had foam &pus in my urine.
