Hi, I have a history of high blood pressure and migraines. Few times within past weeks I woke up and was unable to see fully out of my right eye. This goes away after minute or less. I also have weakness on left side of my body and palpitations that EKG showed within normal limits. My doctor is sending me to get stress test done, however there are symptoms going on in my head that are very scary. I tend to have a feeling of lightheadedness few times throughout the day and just cannot function normally. My eyes are very sensitive also. All blood work is great. I am very concerned.
