Stabbing pains in the kidney

Cr

I have a regularly scheduled doctor’s appointment tomorrow so of course I’ll be asking about it and getting my pee tested but I wanted to ask if anyone else is experiencing this and if it was a UTI. I’m having some intermittent stabbing pains on my left side where my kidney is...or at least I think where it is lol. Anyone else? It comes and goes out the blue and each bout lasts for about 30 seconds.
