Thanks for your query.Based on the facts that you have posted it appears that you have Staphylococcal infection
on the urinary tract
.It seems that organisms are resistant to common antibiotics used in routine practice .But most of the time staphylococcal infection responds well to Penicillin.
Please consult your family physician and start taking Benzathin Penicillin daily for 10 days.
along with anti inflammatory medication like Diclofenac
I think it will get resolved in 10 days.
