I have a vet trip planned for my Spot tomorrow at 9:15am.

I noticed him out of his hide climbing the wall when he fell over. He landed with half his belly up and tried to roll out of it so he was on his stomach completely. He couldn't twist his body the right way. So I helped him out and when I did I noticed there is a 2 inch indent in his spin. As if he he's been smushed in that 2 inch span. I ran my hand along his back and sides, no protrusions, no bumps, no nothing.

He ate a week and a half ago, had a B/M, and seems fine. Drinking water, thermoregulating, etc. The only thing that changed was I moved him from newspaper to aspen and from a small mouse to a 6 day old rat pink. He is able to squeeze himself under the lip of his hide and lift it. A friend of mine thinks he may have lifted it and it somehow fell on him.

While I have him at the vet, I'll have the vet take an x-ray. So we'll see what is going on from there. Keep us in your thoughts, lets hope it's nothing serious.
