Feeling unusual after first dose of Pfizer

Please don’t comment anything bad that has happened to anyone that has gotten the vaccine, I just want to know if what I’m feeling is normal and will go away. So I just got my first dose yesterday. I was fine, just had and still have pain where the vaccine was given. I don’t know if I’m having anxiety now and it’s just what happens when I have anxiety or if I’m actually having shortness of breath. I also have some weird feeling on the left side of my head. Small spasms in my left leg here & there.
