I've had my african clawed frog for 10 years now, and it is only now that he's had a problem with his setup. I'm devastated that he may not pass these rocks, and was wondering how much vet bills would cost me if I were take him in to get them removed.

I have removed the majority of the gravel from his cage (there are a few tiny bits that I can't get out still left) and am fasting him as of two days now. He still seems swollen on one side, so I am worried they are going to be permanent. He's still very active, doesn't seem to be bothered at all. What do I need to buy if anything to assist him pass the rocks, and if all else fails how much is a vet going to cost me and where should I search for the correct vet?
