Stuck with this stone for months :(

Hi everyone, this is my first post here but I’ve been a stone-r for over 20 years now. About 3 months ago I started getting this dull nagging pain down in my lower abdomen, and since I don’t have a urologist at the moment I went to my primary care Dr, who ordered an xray that turned up a 3mm stone still sitting in the kidney. Over the past couple weeks the pain has gotten worse, so my Dr ordered a pelvic ultrasound (to rule out issues with my lady bits) and my insurance finally okayed a ct scan for tomorrow. I couldn’t get a urologist apt for a month. Does anyone have advice on getting this thing to pass? From what I read most urologists would recommend some kind of removal once a stone is being stubborn. I try to stay away from the ER unless I’m literally dying becuaee the few times I’ve had to go in for stones it ran me thousands of dollars in co-pays (and yes, I do have insurance in the US). Should I just ask my primary dr for flomax? I haven’t had a really bad stone in a few years now. I’m 40f and have dealt with stones off and on ever since my first traumatic experience at 16. Nice to meet you ;)
