Thank you for your encouragement yesterday. I needed a place to vent.
I begged the doctor to let me come in this morning to see what was going on. A KUB (kidney-ureter-bladder) x-ray showed the stone was gone (YIPPEE!), and that the stent had slid down and was coiled in my bladder. That's what was causing the unusual level of pain.
So long story short, the doctor removed the stent in the blink of an eye, literally, and I'm a happy camper again. There's still a slight burning sensation but the barbed wire effect is gone. What a relief to have this behind me now.
Bring on the Holidays!
