M, 35, United Kingdom.

Have had migraines and a constant headache for a year now and have had some auras - recently I started getting temporary blindness which starts off as a strobing pass in the centre of my vision and the migrates to the extreme right of my vision in my right eye. Once it has migrated my eyes throb as if there's too much pressure and then the strobing disappears and I'm left with a grey/brown irregular shape in my right eye covering most of the right half of that eye.

  Often this subsides with sleep but sometimes the shape grows and leaves me blind in my right eye, sometimes for 3 days.

  I have a pineal cyst and i'm wondering if this could be the cause.

  PLEASE HELP - my doctor is useless and the Neurologist wants to 'see how it goes'.
