Thanks for the query.
You have not mentioned your age/sex.
If you have nausea
, sweating and flank pain
it may be a sign of infection in the kidney. You need to see a physician/nephrologist
who may do further urine/blood tests and an Ultrasound
of the kidneys to confirm the diagnosis.
Based on the results a change in your antibiotic prescription may be required.
Hope this helps.
