My husband is 77 years old, he has been in excellent health all his life. H quit smoking approx 20+ years ago. He started having hand tremors about 2 years ago only in the right hand which were slight, he is right handed, he always had beautiful ledge-able hand writing, you can t even read his signature anymore. Now he is having what he describes as a sharp electrical shock from the back of his skull on the right side up over his head down through his right eye, he says he can t see out of that eye when it happens.
