I am experiencing mild but persistent right flank pain suggestive of a kidney stone. I have had these several times in the past, but not in many years (currently age 62). Current medications each night, not yet taken, are Flomax x2, ducosate sodium stool softener x3, and atenolol .25 mg. No alcohol or other drugs. I would like to avoid going to an ER, and so far, no pain medication is necessary. If pain gets substantially worse (stone reaches ureter), can I take a Percocet that I have on hand (7.5 with acetaminophen) until I can get checked out by a urologist? If not, I also have Tramadol if that would be more effective. I presume I should not take both. Thanks.
