What are the warning signs of kidney stones?
user
First and foremost is pain. This is what I’d be most worried about, and the pain can feel like you’re being stabbed. You’ll also find you’ll be needing to pee a lot, probably more often than usual. You might have blood in your urine, or feel like your urine has a weird color.  Stones also tend to be associated with nausea, vomiting, or diarrhea.

I’d probably start with your primary care provider, then maybe also get a referral to a urologist.

A urologist would be a good bet, but a nephrologist might be more suitable if your primary symptoms are those of anemia.  You may also find there are other symptoms I didn’t mention, that are unique to your situation.
