Today was just awful.. I got a call from my boyfriend at about 1pm and he told me the ackie monitor he got at the expo yesterday had seriously injured itself. It had gotten stuck in a piece or driftwood he had bought there too and when he came home from work for lunch he found it bleeding in there still stuck. He got it out and the wound isn't pretty. There is a small piece of what I assume is muscle sticking sharply out of his back and his body kind of kinks where this is. It's like a little bump..There is a shallow-ish gash running about half an inch down his body starting at his spine where the lump is. He is only about 1.5" or 2" STV so it's a pretty big cut.. The cut is far enough down that it is not over vital organs other than intestine. The gash reveals what I assume is a rib, and also the space between two ribs. The skin which would normally cover that space is kind of doubled up and I am not comfortable pulling it back over the wound myslef...The vet doesn't have an open space til
wednesday, they told me to use a weak solution of iodine and a q-tip to carefully clean the crud and blood out of the wound. I then put a little polysporin on it. We brought it to my house (I am home more, my boyfriend works full time) and I transferred it to a much smaller, sterile enclosure. Currently it is in there right now, I put poly on it about 3 hours ago, there is fresh water and I have offered some food. The breeder recommended ground beef so I mashed some up and put pure calcium in it. He licked it and sniffed it a little. He is usually very alert but you can tell he is in pain. He can move his tail but doesn't seem to be able to move his back legs very well, he's mostly dragging himself around and will kind of roll over while doing so. I saw him vomit as well. I am not familiar with monitors and I didn't buy it, I don't know a whole lot about them. Please help!!! I feel so bad for the poor little thing

Is there anything I can do to help him right now?? What is the best thing I can be feeding him right now? Supplementation? I know to keep the temps high but what about humidity? (should be round 55%) Can I mist?
I unfortunaltey have no pics right now as I rushed to my bf's house when he called but I will try to take some. I'm so worried about it.
