You have to admit, you've rather tied our hands now, haven't you? It's like going to the doctor and telling him to fix you, but not giving him any information about where you're broken.
We need a lot more information:
how this baby is being cared for
Quite often baby tortoises look a little puffed up. It might be nothing, it might be water retention, it might be kidney failure. Unless we have some idea of how this baby is cared for, we can't even hazard a guess.
I think what we might need is a bit more detail. It would be easier to help if you seemed like you wanted it. I'm far from an expert but I know it would be helpful to have more information, like some of the things you've already been asked to provide. Can you share a pic of the enclosure? Is your tort acting odd? Is it losing weight or feeling soft? Is it eating normally? I probably won't be the one that has the knowledge to help you, but nobody else can help without more info.
