Thank you for the additional information. It sounds like your kitty is uncomfortable (shaking and not eating normally), and since x-rays and blood tests came back clean I am wondering if it might be due to a soft tissue injury. She could have pulled a muscle in her back or neck which can explain her symptoms, including the stiff walking. I think it would be a good idea to call your vet and ask for some pain medicines to make her more comfortable. You should try to restrict her activity level as much as possible, no running or jumping, especially when the pain medicines start working and she feels better. If after a week she is not showing any improvement, it's time to consider things like tick-borne diseases or rarer problems. I mention tick borne diseases because they can cause generalized discomfort, lethargy, inappetance and joint pain. Even if there are not any ticks on your kitty you could have missed one at some point. There is also an illness called feline infectious anemia that cats can pick up from fleas that causes similar symptoms. This illness can be difficult to detect, and sometimes treatment is started even if there is no conclusive diagnosis. Treatment consists of the antibiotic doxycycline. Please see the following website for more information on feline infectious anemia.
If a urinalysis was not run, you might want to consider asking your vet to check for infection. Sometimes cats will have different presentations of illness, and to be thorough her urine should be checked if she continues to have trouble. Please let me know if I can be of further assistance.
