Hopefully everything is ok! Keep a close eye on him. Sending a stool sample is a good idea. You can at least eliminate the possibility of parasites. You may be able to find a local vet that will run the tests for you even if they don't treat amphibians (parasites are parasites). You can just drop off the stool sample and they test. It costs a lot less than a vet visit.. maybe $10-20, depending on the vet and whether they do the test in-house or send them out. It can give you piece of mind, cost less than a vet visit, and doesn't stress your frog out. Trips to the vet are stressful for frogs; if there is a serious problem then of course you should take him to the vet. But often it is hard to tell. I often worry about my frogs, especially after my pacman Grif became ill. I keep a close eye on my frogs and watch for any changes in behavior, appetite, environment, etc. It is often hard to make the call of whether a vet visit is in order. Go with your instinct. No one knows your frog better than you!

I also sympathize with the difficulty of finding a vet that will treat amphibians. When Grif became ill, it took me two days of frantic searching to find a vet (even though I live in a big city) and another two days before they had an appointment available. It is a very good idea to at least have a vet who treats amphibians lined up should you ever need one.

I hope Kriby gets better! Please keep us posted!
