I have had an undiagnosed problem for a few years, and am wondering if it's my kidneys.
I have had frequent urination (10+ times a day) and frequent thirst at night, with the urgency to urinate. I have had past urinary track infections, which resolved on it's own, and I "think" I have chronic, or at least reoccurring infections.
What really concerns me is if I press down on my flanks and back, where the kidneys are, I can feel a very soreness pain.
I have also gained weight significantly over the past few days, to which appears to be water retention. Also my blood pressure has risen, especially the diastolic figures - to the point I feel my head is very stuffy.
I have had several physical blood tests, urine tests, and they all came in border line high or low... For example RBC was 4.7, borderline low. WBC was 10.3, borderline high . Should I ask for GFR or Hemoglobin tests?
Please advise if you know the symptoms, and what I should do (or can do) in the mean time? Any comments highly appreciated!
