Re: White specks in urine
Hi. I had many episodes of urinary urgency, with substantial discomfort, yet wasn't testing positive for UTI's. My urologist even considered testing me for interstitial cystitis, but held off because I was a mess on all fronts. Then I was dx'ed, started Plaquenil, and have had hardly any issues since.
If I feel some discomfort coming on, I watch what I eat & drink. The standard diet reco's for Interstitial Cystitis used to help me somewhat (e.g., avoid spices, acid foods, caffeine, carbonation, alcohol, etc.) If urologist &/or nephrologist haven't come up with anything, you may want to experiment with diet changes & see if that helps.
It can get miserable, I know...! Good luck! Sincerely, Vee
