My cat got vaccinated couple of days ago and is shaky and sensitive to her hip area!!?

I got my 10 months old cat to a vet couple of days ago and she got her first vaccinations there. She had totalbof three different shots and I think some were shot around her hip area or shoulders. I do not really remember...

I noticed this afternoon that she was shaking her body lightly as if she is cold, and it is definitely not a seizure. She's an active playful cat but eversince the shaking stopped, her movements have been really slow and careful then before and she turns aggressive when I try to pet her ESPECIALLY around her right hip area. She still eats and drinks fine and somehow manages to slowly climb and jump on her cat tree but she is definitely moving slower then usual.

Could it be that her right hip is hurting from her shots? I heard that rabies shot which she got can have some side effects on cats.. i thought it was weird how the symptom started just recently instead of the day she got the shot. I'm taking her to vet tomorrow, but I just wanted to have an idea before i talk to the vet. She haven't been shaking ever since that one time. Thabk you so much!!
