Hi, i have upper right quadrant pain below ribs with right flank pain on and off for 6 started off as a dull ache but got worse, bloods are fine. no gallstones, previous appendix removal, no temperature, i have had high blood pressure for 8months?

Hypertension at 24 years old is likely secondary hypertension so we need more info about what the imaging tests have been done for work-up. If you do not have a CT scan of the abdomen with IV contrast, it should be done if there is no contraindication. By the way, your pain has been present for how long, 6 weeks or 6 months.

Even with normal lab testing and no evidence of visible gallstones, the gallbladder can still be a cause of pain. I would also consider the possibility of a kidney infection or kidney stones. If you continue to have symptoms, you should return to your primary care doctor for further testing. Good luck.
