Started with uncontrollable eyelid twitching, eye pain, darker vision (being in regular light but everything looks darker) fuzzy light headed feeling, dizzy and off balance a lot and to the point I wanted to pass out. And lastly headache as more sever. This all has been gradual. Do I need to be concerned? The eyelid twitches non stop now. And now I am finding my right arm is starting to do the same. It gets tiring when thing move and feel like this. Not able to get a good sleep anymore.
