vestibular testing/electrodes as catalyst for trouble?

[kgs123]

I did my vestibular testing and electrodes test (the one for the brain stem) on Tuesday of last week. I had never presented with problems before regarding nerves, etc. I know my mass is pressing against my facial nerve but I never had issues. Since Wednesday, I've had pain in my ear, serious pain in my jaw and now my jaw on the right side is numb. It's so bad I've got trileptal to take now. I'm unable to sleep and it has impacted my daily activities. This is all pre surgery

Has anyone's testing been the catalyst for difficulties? Maybe it's coincidence but I'm really bothered that maybe they're connected.
