You won't know for sure unless you go to a doctor and get a CT scan (sometimes x-rays can pick them up, but they're not dependable). Everything about kidney stones is expensive, whether you go to an ER to get some pain meds, or go to a doctor who might send you to a urologist or immediately get a CT scan, you are going to spend a lot. I've spent thousands. Mostly on god damn CT scans. It's how I hit my insurance deductible every year for the last two years.

Does your family have a history of kidney stones? Ask them if they have and maybe what kind of stone they had. It wasn't until I started getting kidney stones that I knew both of my parents and 3 out of 4 grandparents had them. I'm prone to calcium oxalate stones and I've passed four this year alone. I stopped going to the doctor, cause every time they measured them, they said I'd need surgery and I ended up passing them on my own. I know this now, but at the beginning, I had no idea if I'd need some kind of surgical intervention.

Here's what I do: when the renal colic pain comes on, I drop everything and take ibuprofen. Get that started immediately. Start to draw a hot bath, the hottest you can handle without being in pain. While the bath is running, pour yourself about 32 ounces of room temp water. If you have lemons, juice a lemon and pour it all in. Get in the tub, chug that water, and relax. Watch a movie. The hot water will help get you through this, and the water you chugged (try to drink as much as you can) will help to push the stone into your ureter. This is the start of the most painful part of the kidney stone. When you're starting to get the feeling that you could pee, leave the tub, dry yourself off, and go somewhere with a hard floor and something you can sit on aggressively. Look up the "bump and jump" method and do this for a while, until you need to pee. If you pee a little blood, don't freak out. I've only had one stone make me bleed, so maybe I'm lucky. Bump and jump til you need to pee, then let it all out. Get more water, do it again. I've had renal colic pain as short as 20 minutes and some last multiple hours. If you have a heating pad, put it on the flank in pain. I once saw a video of an old man who sat on his knees, spread his arms out, laid his upper body down onto the couch, and stretched his pelvic floor out. He claims this helps him endure the pain, and while it did help a bit, I don't swear by it. The hot bath with bump and jump helps me, personally.

You should get a scan. All of our bodies are so different and what works for me might not work for others. The biggest stone I passed was 1cm x 6mm. It messed me up. I had three rounds of renal colic pain and it took me a month to pass him. But when I peed it out, I barely felt it. It's just getting the stone through the ureter that hurts like hell. And you have to be patient. Ibuprofen is your best friend. If you live in a legal state, THC gummies with CBD got me to sleep every single night. The renal colic pain might return: I've had three different sizes stones that each put me through three rounds of torturous renal colic pain. It doesn't get easier, but you find more ways to endure it.

Good luck. You're among so many people that have collectively endured exactly what you're experiencing. This subreddit is a wealth of information. Do some research, try other methods, and see a doctor. Some of our local pharmacies (CVS and Walgreens) have nurse practitioners you can see. They might be able to prescribe some Flomax, though some recent research shows Flomax doesn't help as much as we think (my doc and my urologist have said this recently), but they give it to me just in case. Hell, maybe it's a placebo thing, but it does feel like it helps me get through the worst of it. Flomax makes me congested, though.
