Look over your entire body. Is there an infected cut? Might you have the beginnings of toxic shock syndrome? Have you been bitten by some little critter? Please do not take those symptoms lightly! I would go to urgent care and be seen right away, if it were me. I've known too many situations that become worse that are seemingly benign.
There are things that doctors notice that we might not. The best place for you is with a doctor right now. And anything else going on will make MG worse.
I hope you'll be okay!
