Hi everyone,
I have been dealing with bilateral kidney pain for seven months now and am in desperate need for help/advice. From June 2020 to February 2021 I had six UTI's all treated with cranberry juice and lots of water. Did feel occasional twinges in the left kidney after the fifth one but mostly the juice and water seemed to work until the sixth UTI at the end of February when I started feeling pain in my left kidney and a couple of days later in my right one as well. Started with the juice and water again, the UTI symptoms went away in about a week but the kidney pain became worse, to the point that I could feel my kidneys heavy and inflamed, even touching the kidneys area was painful. Eventually I had a urine test that came back negative, then another one positive but no culture was done, then a couple more negative. From the beginning, the pain was on and off, hence the delay in starting antibiotics as I thought it was going away plus, after the negative urine test, the family doctor dismissed it as back pain so I only started antibiotics 18 days after the onset of the infection. After about a week of antibiotics I did not feel my kidneys inflamed anymore and the pain subsided a bit but was still very bad, debilitating. I took antibiotics for 12 days but there was no further improvement after the first week. The pain also came with nausea, hands tremors, lost 3kg/7 lb in a very short time although I was forcing myself to eat and spent most time in bed. The pain was, and still is bilateral, deep, dull and diffuse, and synchronous. Duration, intensity, location is the same in both sides at the same time. The pain is deep in the back in the kidneys, and/or flanks, and/or front just below the ribs. The pain comes and goes, alternating between periods of calm with very vague pain or no pain at all, and periods of pain, but overall mostly pain of various degrees of intensity. From the beginning I also started having clusters of foam/little bubbles in urine, and lately my urine is always cloudy. No protein in urine, had blood and urine tests that came back mostly normal, but with a drop in eGFR at 85 (my eGFR was always over 90 or over 100), and low serum urate/uric acid (about 17% less than the lower end of the range), and high amorphous crystals in urine. Had a CT scan and a DTPA Lasix renal scan/renography that did not show anything abnormal, just the eGFR low again at 86 although I was very well hydrated during the Lasix renal scan. Also a cystoscopy, normal as well. I used to go to the washroom once per night but now I go twice although I drink very little in the evening and stop drinking one hour before bedtime. Also, lately I need to use the washroom very often, especially in the second part of the day although I drink less then. Overall the urine output is higher than the fluid intake. I don't drink coffee or alcohol and do not take diuretics or other drugs.
The pain has gradually decreased in intensity in the first few months but have not seen much improvement over the last three months and it is still bad enough to affect my life. When it comes it lasts for hours and days on end with very short periods of low intensity and even then, it is very unpleasant. It still comes with nausea, weakness and lack of energy. A lot of times it feels like a burning sensation. I finally saw a nephrologist in person mid August, said it could be inflammation that goes away very slowly, that biopsy might be an option but not indicated and that he was sure it probably won't show anything anyway. I later called him when the pain got bad again and he said there was nothing wrong with my kidneys, same from the urologist and family doctor. Not sure what made the nephrologist change his mind. As though the pain I am dealing with is not enough, the whole experience with the doctors is very frustrating, almost not believing me, appointments only over the phone, months until seeing the nephrologist in person. The nephrologist even said that if I had pain I wouldn't be able to talk. Now my family doctor says the inflammation moved from the kidneys to the tissue around the kidneys. All this just based on the fact that the tests showed nothing wrong but the only test that would show interstitial inflammation or kidney scarring is a biopsy so even this is frustrating to hear the doctors say there is nothing wrong with my kidneys when I did not have all the possible tests and everything points to the kidneys (urine appearance, washroom habits, drop in gfr).
I am sorry for the long message but felt I had to explain it all as I am at the end both physically and psychically, not sure if I will ever be free of pain and be able to lead a normal life again, and I don't know where to turn for help. Can you please let me know, if anyone here has experienced or heard of something like this? Thank you so much!
