4 days ago, I woke up with a left side eye droop that seemed to appear out of nothing. I am a college bound 17 year old male with no previous serious health issues and I enjoy using the computer. The day before I remember getting off the computer and having this aching feeling that made both my eyes feel like they were going to stay shut. I have had nothing else happen except for the droop, my ct scan and blood work is all fine, and I still have 20/20 vision. Would anybody know what happened?
