Please help, I was woken up in the night with flashing lights in one eye it was like I was blind in one eye only being able to see these lights. The other eye was fine, has the day is going on I have a headache, worse when Iam moving, anyone had this. It was so scary. I am 50 years old and have had terrible anxiety, gastric, dizziness, palpitations and so on for about 4 years now. I am not on HRT.
