Hi!
I hope by now that your kidney infection has responded to antibiotics.
If you are not better, you should definitely go back to your doctor.
Usually a kidney infection will respond quickly to antibiotics.
An ovarian cyst can either get better quickly, or the pain can persist.
Again, if you are not better, you should go back in to your doctor's office.
If nothing else, they can give you something for pain.
In the mean time. or if it comes up again, you can try Ibuprofen, Anaprox, or Tylenol.
Good luck!
Dr B
