Over the last year I have suffered with severe headaches off and on, sinus issues,instances of seeing flashes of light, lots of small dots that move,partial loss of vision in one eye,muscle weakness, and pain,pickiness in hands,feet,and legs,mild shaking in hands and legs sometimes,overactive bladder,eye twitching, and most recently one large pupil and one normal size pupil. I was checked months ago by my eye doctor when seeing the flashes of light and dots, and everything was normal. With all the symptoms on top of the unequal pupils, what could this be?
