Swollen Frog? Please Help!

[Meer]

Oh no I have been using horrible water for my frog!! Could that be contributing to what's wrong with him? Where could I get things like R/O-rite or Electro-rite mentioned in that other thread to treat the R/O water? I would really prefer that to treating my yucky tap water.

My frog was an adult when I got him, although I think he was not full grown, he got bigger the first few months or so that I had him. That would make him four years old at the youngest. I'm trying to prepare myself that this may be the natural end of his life. But it might not, I'm not giving up yet. I want to do everything I can for him.

I really don't want to mention the name of the forum I was on before or say what happened. I shouldn't even have brought it up. It just wasn't a good fit for me personally.

Anyway, I am just waiting until morning to see about going to a vet. (it's 1 AM now, yay for insomnia )
