Taking Macrodantin for cystitis (48 hours so far), bladder/urethra symptoms starting to clear (but not gone) but have mild kidney pain (new) - should I wait until antibiotics finished before panicking?

sounds like you are already on antibiotics for a urinary tract infection.

a urine culture would still take 2-3 days to come back.

it would be unlikely for you to have accending infection up to your kidneys to cause a pylonephritis infection of the kidney while on microdantin antibiotics already.

in rare cases of urinary tract infections, the bacteria can be resistant to an antibiotic like microdantin. this is checked for by sensitivity and specificity testing on the urine culture. hopefully this was done for you already when you had a urinary analysis and urine culture. ask your doctor if this was already done for you

new kidney pain now could be a small kidney stone which is being passed from the kidney down the ureter. this can be checked for by a kidney ultrasound scan or a thin slice renal pylogram CT scan of the abdomen which can see small kidney stones. kidneys stones can also cause blood in the urine and this can be checked for as well.

let me know if you have questions.
