Aaaaah thank you guys so much!! You guys are such a big help oh my gosh! It turns out that that white-ish stuff around his leg is new skin, and his wound looks like it is slowly healing up!! His leg is far less swollen too. I'll try and get some of the unflavored pedialyte stuff tomorrow...I hope the pet store has it! I just started feeding him worms today, it seems he likes those better than crickets because he swallows them almost immediately. Still wont eat them off of tweezers, however.
Here's a picture I took of him, he's lookin' good! (you might have to click on it to see it better, however)
