Ozzy is a rescue that we've had for almost a year. His right front leg is truned in slightly and his tail is crooked from not having UVB exposure from the previous owner. I noticed two days ago that his left rear leg was a little swollen, I checked him out and he could still use it, today he's not moving it at all. When I try to pet him he puffs and opens his mouth, I think he would bite me even though he's the sweetesst thing ever. Could this be due to his old MBD problems??? He's ate some of his greens but is uninterested in his crickets. Any Information would be helpful, I won't be able to get him to the Vet until Friday, and then I'll have to find a good one that actuallyknows what they're talking about. HELP!!!!
