Kidney stones

Have any of you had idney stones before? How lomg until the pain went away. I was hospitalized for 4 days for kidney stones. I'm 27 weeks pregnant. The pain was way way worse then birth. And I gave birth unmedicated. It also hurt worse then the time I broke my elbow in half. So far I have passed two stones. How many do you usually pass? I just want to feel normal again :( I can barley even move. Every time I move the pain get worse. Have any of you death with this?
