Why Did I Suddenly Feel Numbness, Tingling Sensation And Weakness All Over My Body Apart From Throat Infection?

Hello, Today I suddenly felt numbness and tingling and weakness all over my body, can’t get better for about an hour until 9-11 came and injected me magnezium. Now I feel better. Why can this happen? Besides I have a throat infection like white covering in the throat and swollen tonsils. I took antibiotics, maybe it is antibiotics’ side effect?
