Hello,
From the symptoms the important possibilities that need to be ruled out are urinary tract infection, ureteric stones and urethral syndrome. Urethral syndrome is a primarily female syndrome in which women suffer from irritative bladder symptoms (urinary frequency, urgency, burning , and a hesitant or slowed urinary stream) in the absence of any objective urologic findings. In this the diagnosis can be made only by the proper collections of urine specimens from both the urethra and the bladder. These specimens will reveal the presence of white blood cells in the urethral washings, while the midstream (bladder) specimen will be free of cells.
Is suggest you to consult a urologist and get a complete urine examination, urine culture, urine from bladder examination and a CT abdomen done.
I sincerely hope that helps. Take care.
I forgot to add that i also have hardly no blood in my urine. they said there were traces, but not an abundant amount that a kidney stone would create.
