This could be serious. I have seen cats come into the Vets with broken legs,hips and feet. Definitely needs to be X-rayed! Has he been outside where he could possibly been hit? Or in a cat fight? I would keep him in a cage with constant care until you can get him some help. I'd like to know how things turn out, leave a msg. In my shout out box. Hope I was some help!
The best thing to do if he won't let you touch it is to go to the vet
Bring him to the SPCA and ask their advice?
Meanwhile leave the cat alone in a safe environment where it can feel secure
