Hi, welcome to our site. I am Dr Saumya Mittal, MD.
Read your query. That is a very significant question and i appreciate your problem. I will try my best to answer your query
There are two possible causes that may have caused the symptoms.
One is the possibility that the infection has probably co involved your genitourinary tract and the infection of this tract is causing you
backache, as many gyncological conditions do.
The other possibility is that the infection has spread up into
the urinary tract to affect the higher urinary centres.
I would suggest a culture of the urine so that an accurate antibiotic can be eventually prescribed, and an MRI/USG to look up the local source of pain.
I hope this helps you. Inform the reports mentioned above/if any other so I can be of help further.
I have given you the answer to the maximum considering the information provided. The results of the tests could further enhance my answer to you.
