This can still be from the inflamed ureter; and at this point i will suggest you to continue anti-inflammatory pain medicines like ibuprofen or naproxen for another week. See how this behaves in next few days and after stopping the medications.
And drink lot of water meanwhile.
A hernia is least likely here, since it presents with expansile swelling in the abdomen and causes pain only if it becomes significantly enlarged.
A pinched nerve in the spine (due to a prolapsed disc or vertebral degeneration) can be another cause, and an MRI of the spine will be the most useful test to diagnose this with certainty; but i would wait for another few days while taking anti-inflammatory agents before proceeding with further tests.
