My mother has her 3rd UTI in 6 mos. The first two landed her in the hospital and she was septic the first time. The signs are very subtle - lethargy, loss of appetite, chills. Her doctor came yesterday (she makes house calls for seniors) and all my mom's vital signs were fine. But she believed me when I said her vitals were fine last time, until she got to the hospital and then they were alarming. Doc prescribed a broad-spectrum antibiotic and my mom took the second dose today. So far I don't think she feels much better. The last two times there was a "sign" that we had to call 911 - i.e. she had a dreadful episode of diarrhea and vomited. There hasn't been anything dramatic this time - yet. The last thing I want to do is call 911 again, especially when the oral antibiotics might kick in soon. It is so traumatic for her and for me to deal with the ER, ambulance, etc. So I don't know what to do. I'm terrified of another sepsis episode. I guess I will ask the doc to order a blood test, but that takes a few days to get back.
(FYI, the cause of her repeated infections is a large kidney stone. Docs are not confident surgery for that is good idea due to her fragile health.)
