hello, thanks for writing to HCM.
I understand your concern, and know that the pain from a
urinary tract origin can be quite severe. I would think of an untreated infection/small uretric stone first.
I am unsure of which tests you have been through, but I would recommend a
Complete Blood count (for the infection), a urine routine and culture/sensitivity (to see the specific bacteria and sensitivity to different antibiotics) and renal profile.
Also a CT urogram where the entire urinary tract can be imaged, is more sensitive for infection/calculi etc than an
ultrasound.
Also a non-urinary cause for the pain can be picked up.
You must try convey your condition and discuss this with your doctor or anyone available as soon as possible.
Till then maintain adequate hydration, and continue with medicines prescribed.
Wishing you a quick recovery. Do write in with any doubts.
Take care.
