Can Cervical Injection Cause Fatigue And Feeling Of Fever?

Hi there. On October 7th, I had a cervical injection due to chronic pain in neck/shoulders area (several herniated discs). This is not my first, however 2 weeks after I had the injection I feel as though I have an infection. That feeling of having a fever but not running one and extremely tired. It comes and goes off and on, but turned out on October 21st, I went to my primary and he said I had a UTI so he gave me antibiotics. Which helped that infection feeling but then 4 days after finishing the antibiotics I felt the same way. So I went back to my primary he said the UTI was no longer but gave me a Z-Pac which I took and same thing happened. I felt better while taking the med s then within days of finishing I feel that fever feeling and extreme fatigue again. I felt terrible this weekend and am wondering if this could be a side effect of the injection?
