My crested gecko is acting weird :( help!

[obsidiandark]

I have had my crested gecko for several months now, and he's not very old-
Just today I went to feed him and I found him wobbling uncoordinated about the cage, it looks like he just shed his skin and still has some on his feet, he's been compressing himself against the wall of the cage and twisting his body up really awkwardly.. one of his hind legs he's walking on really weird, like it's out of location on the lower leg, but when he's just sitting it looks fine. on a second note the cage is very dirty and i am throwing it out and he is currently in a smaller clean cage- I could use some answers or feedback on this i'm very worried about him
