Anyone else?? Look for advice

So just finished by course of iv followed by oral steroids 5 days ago and my vision is a lot better but eyes can’t focus if something is moving, makes me feel a bit off. Anyways today no eye pain or anything like that but I am having flashes of light in the corner of my bad eye and been going on for about 5/6 hours only thing that helps is ibuprofen.

Is this normal???

Also getting an mri on Tuesday as suspected MS.

My anxiety has went crazy!! I can’t even function it’s so bad just now, constant panic attacks.

Please help ease my mind!!
