HELP!!! my leo isnt moving at all..?

In order for him to move I have to actually pick him up and move him. He doesn't seem to be using his legs at all, one of the front elbows looks swollen or something. He just finished shedding which took over 2 days to do (and I had to help him with that by means of a warm bath to soften the skin). While I was helping the shed come off, the one with the weird elbow was twitching a little and if I pulled to hard on the back legs he would look back at them. He's able to move his tail as well so I don't think he's paralyzed but I don't understand why he's not getting up and moving at all. I fed him a lil bit of reptaide but he didn't eat much. For his size, his tail is plump, he's starting to look skinny in the body though. I keep calcium supplement in his tank which he has been nibbling on (not recently), a moist hide anddry hide. I haven't been able to find a reptile vet in my area... any suggestions?? What's wrong with him?? What do I do??
