Welcome to HCM,
It seems that you are having chronic urinary tract infection
Repeatedly and changing antibiotic medicine will not solve your problem.
This will develop resistant against particular antibiotic.
So it is better to go for urine check up and culture sensitivity test.
This test will give idea regarding causative bacteria and medicine working against it.
After report go for long course of antibiotic medicine accordingly.
Take plenty of water to flush out infection.
Ok and bye.
