Any idea what this is??

Since thursday my vision keeps going blurry in my right eye. It happened for about 10 minutes on thurs and I couldn’t focus on anything at all. My colleague said it was like I was looking straight through her and my eyes glazed over. I am being investigated for possible Epilepsy and MS. It keeps happening thought but with pain into my teeth and cheek on the right side of my face. Any ideas what it could be?? I do suffer with migraines but this is totally different to normal, could it just be a migraine?
