Hello and welcome to HCM.
Thank you for your query.
From the description provided, it appears to be a case of ineffective antibiotic treatment.
This could only mean that the specific antibiotic is ineffective in your specific case. I would thus recommend a urine culture and sensitivity examination, which would help by providing a list of antibiotics which are effective in treating your infection, and from this this information your doctor would choose the most suitable antibiotic; which will surely show an improvement within 24-48 hours of initiation of treatment, and completely rid you of the infection within 5-7 days of treatment.
In the meantime, please consume plenty of water, in order to avoid
dehydration. Also, I would like to get an
ultrasound conducted of the region, just to be on the safer side.
I hope I have succeeded in providing the information you were looking for. Please feel free to write back to me for any further clarifications at: http://doctor.healthcaremagic.com/doctors/dr-shoaib-khan/64581 . I would gladly help you.
Best wishes.
