Followers of this blog are aware that I have a chronic problem with kidney stones and that I have correlated the triggering of their passage with flying. Shortly after returning from Turkey a week ago, I began experiencing pain which has increased every day since. Last night, I decided that I would seek medical intervention on Monday if the pain did not subside. Mercifully, I passed the pictured stone this morning. It measured 5.6 x 4.5 mm, one of the largest for me so far. I apologize for including this topic on my blog but I do so to chronicle my history with stones which is helpful when discussing the topic with my doctors.
