I need help asap, my iguana was hitting his side with his left arm for no apparent reason, I had looked and noticed he had a bit of shed on his foot so I had assumed that was the problem. This morning, he appeared perfectly fine, he was moving regularly and he had stopped hitting himself so I was no longer worried, but later this evening he began limping! He now seems to have absolutely no movement in his left arm, it is limp, he runs on it but only if he feels it is ABSOLUTELY NECESSARY, otherwise he avoids getting on it as much as possible. I'm worried he has a broken arm, or that he had pulled a muscle or something along those lines. The problem started tonight at around 9 PM, is it something else or has he for sure injured his arm badly? I'm going to take him to a herp vet as soon as I've got the money, but I want to be 100% positive that this is a serious matter before I decide to spend any money, as we're absolutely broke....any help at all would be greatly appreciated! I know it's very very likely to be an injury, I'm so incredibly worried about him..
