Can't have lithotripsy "the thumper" (ultrasound) when they did it my first go round they thumped my kidneys so hard with the sound waves I almost bled to death so a big no no for me, nothing but surgery from there on out unfortunately, yeah the most intense pain I've ever felt for sure, going through surgery w/o pain meds is a living never ending nightmare, especially after waking up from the anesthetic. My digestive tract is screwed up so no opiates or ibuprofen, nothing but Tylenol, ugh !!
