I have a twitch or "throbbing"vein or artery right above my right eye. You can see it pulse & then all of a sudden stops. I have also had horrible headaches while this is happening, maybe migraines (nausea, sensitivity to light). This has been for about a week. Sometimes i feel light my vision is also not as good during my headaches. I have had extreme stress and anxiety lately, I was wondering if this was just a result of that.
