I've been sick since June 17th, with varying symptoms. Long story short, I ultimately had an ultrasound and CT scan done. They found a 4.5 cm cyst and 6 mm stone in my right kidney. Two days ago, even with hydrocodone in my system, I was feeling stabbing pains in my right side. Yesterday I woke up at 4 am with severe pain in my groin and it felt as though the pain was moving down my side. I thought my stone was passing and was so happy to be done with it! At about 3:30 in the afternoon, I felt something pass during urination and luckily it was caught in the strainer. It was an oblong piece of what looked like a whitish-yellow mucus with some blood on one end. I put it in a small bag to bring to my doctor in case there's sediment in it. Since then every time I urinate I pass at least a small amount of this mucus, either in specks or a more liquid form. My urine is cloudy, where before passing the initial mucus it was clear. I have a small amount of occasional stabbing pain still, but feel significantly better since passing the initial mucus. Have I passed the stone without realizing it and am now just passing what's left from infection?
