A prayer request from us

I can understand why the Lord hasn't allowed us to have a baby to bring home yet......Mark is in the hospital with kidney stones! He called me from the office yesterday morning around 8, asking me to come pick him up.
We ended up going to the hospital (this is round 3 for his ER visits). This was the worst pain yet. I felt so bad for him!
To make a long story short - he was admitted for observation yesterday morning for pain control reasons. He finally was pain free by the evening but was struggling with nausea and vomiting.
I figured that if he could get through the night without any more pain - we'd be home this afternoon. It wasn't to be - Mark called while I was getting ready to come to the hospital to say that he started having pain again about 6:30am.....and it's continued off and on ever since.
He's an inpatient now, the hospitalist is going to try him on some different medication to see if that helps pass the stone.

With that said, I'm sure that you can guess our prayer requests = 1) that Mark would pass the stone and 2) that I would NOT go into labor - which I don't think is imminent, anway. We'd be very grateful for your petitions.
Just to let you know, I do have a friend "on call" if I would go into labor.
