Could Having Stones In Kidney Lead To Burning Sensation While Urinating?

Hi. Friday I noticed it burned when I urinated. I planned to get some cranberry juice & drink more water because I thought maybe it was a uti. Then Saturday evening I got to feeling bad and had horrible cramping in my lower abdomen. Not menstrual cramping. It was so bad I soaked in a warm bath with epsom salts to try to ease the pain. Then I passed some small particles when I urinated....looked sort of like sand. The pain eased up & I was just sore. There was a little blood on my tissue when I urinated. It still burns and am sore around my vaginal area. It burns especailly when I urinate. I thought maybe I had a kidney stone break up and pass and was getting better but now I just don't know what it is. Have you ever heard of anything like this? And what can I do at home to treat it?
