Hopefully, your kidney stone problems will be over FOR NOW anyway, with having had your procedure yesterday. No question but that kidney stone pain can be unbearable without pain meds to help ease that pain. I know for me personally it is that way 98% of the time. You'll have to be watchful though as now that you've had a kidney stone, you'll most likely experience more of them as time goes on. Keep drinking plenty of water daily and that will help, but if your body is prone to making them, you'll definitely have this experience again in the future.
As far as the medications you mentioned, I have no idea what they are since you indicated that they aren't sold here in the US where I am and I've never heard of them. Maybe someone else in here will have some info regarding either of them that will be of help to youin answering your question.
As far as the scriptures you quoted, I'm pleased that while you were on the way to the ER with your kidney stone pain that you could think of scripture. In my personal situation, my kidney stone pain is usually so bad that it's all I can do to get to the hospital ER for a shot of Demoral to kill that pain. As a Christian too, I do appreciate your analogy though and I'm glad it works for you.
