Thanks for asking...
He was scheduled to go back to BZ last week and extended a week (to return today). Tuesday, he woke up in much pain, (Dr. Vicki knew it was stones from experience). Went to the ER, where they did x-rays and sure enough.
Got some great pain meds. Then, when he saw the Dr again, he was shown on this x-rays a large unpassable stone. So, he has to go in and get it "zapped". That will be Tuesday and the Dr wouldn't let him fly for 7 days following. So he is stuck here until Oct 12!! (Which is conveniently my return date too!)
At least we did catch it here!!
