I've had my leopard gecko for seven years & just last night my mother discovered that his left testicle area is swollen & red. It also has a scab in the middle. We immediately cleaned out the whole cage & put in a towel instead of the sand we usually use. He's never had any problems before so we're pretty unsure of what to do exactly. We put Neosporin on it last night & again this morning & we also just got done soaking him in a warm water bath for 15 minutes. We plan to do this again later. While he was in the warm bath, I massaged his abdomen and even his swollen area for a little while. I'm at a loss for what else we should do. I just don't want him to get any worse. His tail is bigger than ever before, and it scares me because I don't want an infection to spread throughout his little body. He seems to have lost his appetite, but he's still drinking. I called a DVM reptile specialist this morning & left a message. Below are some pictures of the poor guy. Any advice would be greatly appreciated!
