So m a few days ago I came home and noticed my chameleon not lifting one of her front arms like she normally does. It almost looked like it was dislocated. I tried doing research and found mbd but now I'm not sure it's that. Today I noticed that the joint area turned almost black and spotted and there is some cloudy pus coming out of it. She is still getting around good, eating,drinking all that but I'm really worried and don't know what to do. Please help!
