The never ending pee - Msk

Hi ! It all started when my dad died. I was very stressed and my colon was on fire. I went for an echography...I thought my spleen was exploding.. but eventually my spleen was really fine! The doctor moved the thing all over my torso and then he stopped like 5 minutes on my kidney, staring at the screen in silence. He didn't know what I had and I went to a nephrologist who, after other exams and urine tests gave me the Msk diagnosis. I never had symptoms. Only one: I always have to go to pee. It gets worse at night when I am laying on my bed
