Hi, I have a long history of uti s that spread to my kidneys. for over 10 years. They can not figure out why. I have constant back pain and have been in and out of the hospital for it at least twice a year. I am sure I have another UTI. I am experiencing bad lower back pain, and urgency when I urinate. I am suffering with diarrhea, urinating only once a day, no matter how much I drink. I dont know what else to do. The ER keeps sending me home, and oral antibiotics are not staying down or working. I usually end up in the hospital because only IV antibiotics will work. I m at my wits end.
