Anxiety of strokes and Seizures

I have had my braces on for nearly a year and get them off in two months. These braces have given me headaches to no end. Lately I have been having a numb feeling (kind of soft, no tingles) to the right of my right eye and weird feeling/pressure in the right side of my head. I also keep thinking my vision is flickering but it's so minor I can barely tell.

I have never had a headache in my life until I put these braces on so theres a tiny bit of reasurrance there.

But I'm scared if these head feelings arent from my braces.

I'm scared I might have a stroke or a seizure and need to get it checked out, but I cant beacuse I have braces and they dont allow MRI's with braces for safety reasons. All of this along with the fact that I have recently diagnosed SCDS in my RIGHT ear terrifies me.

I'm miserable every night I lose sleep over this.
