@amira It sounds to me as if it's time to actually see the doctor. I googled side effects from the shot and there was some good info on these sites::
https://www.healthline.com/health/shingles-vaccine-side-effects#outlook
https://health.usnews.com/health-care/patient-advice/articles/2018-06-15/a-new-shingles-vaccine-prepare-for-harsher-side-effects
https://www.cdc.gov/vaccines/vpd/shingles/public/shingrix/index.html
The last link has this info in it:
"If you experience side effects from Shingrix, you should report them to the Vaccine Adverse Event Reporting System (VAERS). Your doctor might file this report, or you can do it yourself through the VAERS website external, https://vaers.hhs.gov/index.html, or by calling 1-800-822-7967"

I suggest that you call that number to report the side-effects that seem to be from the shot or go to the website.

According to these articles, the side-effects should not last a week. They all say 2 - 3 days.
I hope you get some relief and can find out if the shot is causing your symptoms or it's something else. It would be helpful if would let us know how things go as you move forward.

@dablues These links may be helpful to you also.

Gosh, I got a flu shot and shingles shot more than a week ago and I can’t shake the low grade fevers and stomach problems. I’m so very worried, so much so I got a Covid test which was negative. I’m so worried! What is happening?
