What can be done to help a lizard that has suddenly become lethargic? Could it be a bad batch of crickets?
It is lethargic, has a bump on its back and doesn't move its legs. All this is just now happening.

I would say impaction. All of these are signs of impaction. Although I don't know any thing about green amievas, I would say go to a vet to get the problem figured out and cured asap.

Lethargy is not a good sign! There are certain internal parasites that manifest themselves as bumps on the back. I would say a vet trip is in order.

Lethargy could be due to parasites, improper temperatures, a lot of things. The lump could also be caused by parasites, or since there's both a lump and loss of use in his limbs, it could be a spinal injury. A vet trip will be a necessity for this little guy. If it is parasites, its probably something he's had from the wild. However, since the problem is just showing itself now, there is the possibility that something with his habitat or diet isnt hkeeping his immune system in top knotch condition. Could you give a rundown of his diet, supplements, and his cage setup?
