i have been experiencing vision problems in my right eye for approximately one year, difficulty in focusing (have been to eye doctor & have an updated pair of glasses), but problem persists, i also have twitching of the eyelid in the same eye and occasional pain, i have also begun to experience twitching in my right hand mostly my small finger and some lack of coordination / balance. I am a white 43 year old male, 5 11 190lbs with no medical history other than kidney stones (over 20 years) and do not take any medications. Any advice would be appreciated. Thank You
