I took my male 3-toed box turtle to the vet yesterday, he had runny and swollen eyes. When the vet was checking him over, she pulled out his back leg, and his side was impacted with dirt. She took him to the back to clean it out, and showed me a deep cavity on his one side, where the dirt had been. It is between his front and hind leg, on his left side. It was really impacted in there, and she felt that maybe it was putting pressure on his lungs, hence the infection? He's on antibiotics now, and I have to inject him every other day for 10 days (yikes). I was wondering what caused this deep cavity, and if anyone else has seen something like this? The skin is smooth in there, no signs of a wound.
