We are treating for the possibility of a yeast infection, which could explain the weird mouth feelings...yet look normal in there. . .
And..please back me up on this. With that much antibiotics..the chance of UTI is low..right?
From what you wrote, sounds like you mom lives at her home, as opposed to in a care facility. Has she been hospitalized or had any out-patient procedures in the recent past?
I guess I experienced the worst of the worst with my mom. When she was in her first skilled nursing facility, she kept complaining about her mouth. It was tough to get anyone at the facility to take it seriously. The complaints went on for a couple weeks. Eventually, it was determined that she had MRSA in her mouth (had to have acquired it from that facility, or the hospital before it)
There can be varied experiences with a UTI. It's possible to have a UTI, but the usual initial tests doesn't show it. I have had that issue & ended up having to see a urologist for a period of time.
Certain antibiotics work better for UTI's. There can be some antibiotic resistant UTI's. I think this is more likely to happen when someone is in a skilled nursing facility or hospital. During the last few months of my mom's life, she kept having UTI's. One episode was tested as being associated with VRE (an antibiotic resistant form of a UTI). This led to an episode of sepsis.
I'm not trying to scare you, but UTI's aren't necessarily simple with the elderly. My mom spent the last 5 months of her life in hospitals or skilled nursing facilities. The majority of that time she had UTI's. She would get treatment, but then there would be another round. She has sepsis 3 times. One of those times, they diagnosed sepsis before the UTI.
Anyway, I don't want to scare you. My experience with my mom is perhaps a bit unusual. We couldn't get the care facilities to proactively test my mom for UTI's, after the first couple of episodes. Waiting for a patient to get septic, wasn't a good course of action. It couldn't hurt to have your mom tested for a UTI. I'm sure you will be told it isn't needed, but it could be worthwhile to have it ruled out.
