Thanks for your query. Your history of intermittent pain in the right power abdomen lasting for a couple of seconds and on 3/10 on a scale, the possible diagnosis is :Right Ureteric colic due to a stone in the right ureter with or without urinary tract infection. I would advise going to ER for clinical evaluation, ultrasonography and X-ray of the chest. The treatment will depend upon the reports of investigations; if surgery is required go for it. </s>
