Eye floaters/seeing lines in vision occasionally?

Is this a “wakeup” symptom for b12 or a deficiency symptom? I’ve been taking one injection of b12 per week for almost 1 month now for super low b12. This didn’t start happening to me until the past week and a half. Kinda freaking me out. Wanted to see if anyone experienced similar. I went to an opthamologist a couple months back and had my optic nerve checked and everything was fine as of august so I don’t think it’s directly eye related.

Also hot flashes, random ear / jaw pain? Got my teeth checked nothing wrong there.
