I want to get some more detail information about your problem-
How long the problem is there?
Is there any blood in urine?
Do you any soreness in urethral margin?
Waiting for your reply.
Thank you for the information.
As antibiotic did not help, you need a repeat routine urine examination, culture of urine and a ultrasonography of the abdomen.
Sometimes bacteria may be resistant to the antibiotic you have taken.
As you had kidney stone before, there may be chance of recurrence of stone.
You need detailed investigations to find out the cause.
By this time you should take plenty of water which is good to clear up the tiny crystals of stone or bacteria.
I hope this will help. If you got your answer please press the ACCEPT button and leave a Positive Feed back which is dearer to me. Bonus is appreciated. Thank you.
