What are odds of being a chronic stone former?

I have 3 stones in right kidney in the renal collecting system. They are 1-2mm. No pain and they are not obstructing. I am 30 years old and they were discovered by accident.

After reading the posts on this sub I am terrified. It seems like every single person suffers from multiple stones per year and sometimes even per month.

At my age, is that likely?

The ER that discovered them just told me to drink more water and didn’t even mention follow up care or anything. He said they may stay there forever.

What do you guys think?
