[|Human|] Two months ago I had what I was sure was a normal bladder infection. All the typical symptoms were present- painful & burning urination, frequent urge to go, dull pelvic pain, etc. I treated it with the typical home remedies (increased water intake, cranberry juice, and OTC urinary supplements) that usually take care of it fairly quickly. After two days, I was almost back to normal when suddenly I noticed my urine looked like straight blood from a vein (I was not menstrating), and I had moderate flank pain. So the next morning I went to a clinic knowing it had gotten into my kidneys. After the nurse practitioner collected the urine sample, she came to the same conclusion that it was a complicated UTI which had traveled to my kidneys. She prescribed Ciprofloxacin, but sent the sample in for culture testing anyways. After two days on the Cipro, the majority of my symptoms cleared up. But then the clinic called me back and left a voicemail saying the culture test came back negative for any infection/bacteria, although my there was a high level of protein in my urine, and I could discontinue the use of my prescriptions. I did as they said, and the burning & bloody urination never returned. However, to this day my kidneys are still swollen and tender. A few days ago, I also noticed there is now a bruise directly over my left kidney. I have not passed any kidney stones, nor do I feel as though I will. Any ideas on what could cause this? Should I see a doctor?
[|AI|]  Good Day, and thank you for being with Chat Doctor ! Yes a consult with a urologist is necessary in your case. I would also urge getting a PUB ultrasound or a ct scan to check for stones or rumors. Blood I the urine is always a distressing symptom and warrants further testing. Another urine sample should be taken to check for infection. I hope I have succeeded in providing the information you were looking for.
