Hello. Really worried. Yesterday morning i had a flashing light in my right eye which lasted about half an hour. Then had really bad headache which still isn't fully gone. Now today feel so groggy and my left eye keeps twitching. I am so worried there's something sinister behind all these symptoms plus my longstanding problem with facial pain. My eyes now really ache. I don't want to go to the docs as they will just say headache so whats the point.
