What you are describing could be a couple of different things. First possibility is that the cat is seeing or hearing something you are not. The second, more likely thing, is that this is a pain response. I would recommend treating the cat with one 81 mg asprin, that's a children's or heart asprin. This is acutually a very effective treatment given at a rate of one tablet every other day. If you see improvement with this treatment it is probably a pain response, therefore this will probably warrant a trip to your vet to find the source of the pain. Please contact me if you have further questions.
