Help for immune response

I’m submitting for my mother who had first shot around 3weeks ago. Approximately 3days after started developing these symptoms.

very bad urinary infection

can’t sleep

nerves constantly on edge

burning mouth

shingles on stomach ( had bad shingles previously then was vaccinated for it)

sharp pains on sides

I would like advice of any practitioners in the Nelson area please. I feel she is suffering an immune response or attack and would like to know how to treat her. Her dr said it’s not because of the shot.
