Thank you very much for the useful information Allie.
There can be number of reasons for this.
Ovarian cysts again on the top (infected or ruptured).
Appendicitis (which may run a subclinical and prolonged course leading to abscess formation and chronic pain).
Ileocolitis (due to bacterial, parasitic or even tuberculous infection).
Stones in the ureter.
Infection of the urinary tract.
A pinched nerve (in the spine or in the thigh).
Ideally this should be evaluated now, both clinically as well as in the form of investigation like Ultrasound/CT of the abdomen to exactly diagnose the condition responsible for this which will direct a specific and targeted management plan.
At home there are few measures honestly, to help you.
Change from ibuprofen to naproxen (more strong pain reliever) and take up to 500 mg twice daily.
Add tylenol as well in combination with naproxen.
Apply heating pads to the affected area.
Maintain adequate hydration.
Use more fibre (metamucil) and veggies.
Avoid fatty and spicy meals.
And take small frequent meals instead of three large one's.
See how you respond to these changes.
If the pain persists, does not improve or get worse, have this evaluated ASAP.
I would have been worried too if I were at your place, but let me reassure you that this is a treatable condition and carries a good prognosis with appropriate management.
