I am happy to help you this evening.
It could be your appendix , gallbladder or kidney stone.
~ vague abdominal pain that is hard to pinpont
~nausea and vomiting
~pain more under right rib and going into back
~ nausea or vomiting
~more pain in lower back
Your doctor could order an abdominal ultrasound to check you.
He might even order a HIDA scan to check gallbladder function.
If you have severe pain go to the ER.
Best Wishes to you,
Hope you feel better soon.
