I ve had a twitch in my left eye for over 20 years, which rarely goes away. It is mostly in the upper eyelid, put also is around the entire eye. It s my eyelid for sure, (not my eye). Also, lately, the motion causes my forehead & eyebrows to move upward, more so on the right side, & it is visually noticable & I can really feel it. I ve been looking up various twiching disorders on line, & I m not sure if I have myokymia fasciculation or maybe Blepharospasm. I also looked at the possiblility of hemifacial spasms, but I do not have spasms anywhere below the eye. Do you know what this could be & why I ve had it for so many years. It started when I was 14 years old & at that time, I didn t have a computer or watch much tv & I didn t drink much caffine.
