Hi there welcome to the forum. So I can tell just looking at him and seeing the bumps under the skin on his ribs that there is a calcium/UVB issue within your husbandry. He needs a good reptile vet to see what all is going on but the shut down could be from lack of correct supplements/UVB linked in with the injury. We can do the husbandry review for you. If you want to start there while you are trying to get him into a vet that will at least help you correct the cause. Copy paste the husbandry form posted above for you into your reply. Then answer with as much detail as possible. Please add pics of the entire enclosure from the lighting down and more pics of him from multiple angles.
