I did have a "stuck stone" ... ummmm, I believe it was late last summer. I was scared, no so much that the pain was unbearable, but not sure what was gonna happen next. I'd flushed on Fri nite/Sat morning and by Sun nite, I sat here wondering if I should head to the hospital. I went ahead to work on Mon, intending to do another flush the following weekend to see if I could move it out. On Tues morning, I went into a spontaneous flush, passed large black stones and a pile of black sand. Afer that, I began healing.
