I am a 21 year old male and since november I have noticed my right upper eyelid is drooping. It isnt impairing my vision but i can feel it droop and it bothers me. I went to an eye doctor and the noticed my pupil in the eye that is drooping is 2 mm larger in dim light than my left pupil. He referred me to a neurologist and the neurologist didnt think anything was wrong but sent me for an mri on my brain and blood work. Everything came back normal so he thinks its just a normal varience. But for about a month now I have noticed the my right arm and leg feel tight, almost weak but not really because I can play sports and run and do everything like I used to do. What could this be? Any help would be greatly appreciated. AM I just drving myself crazy and thinking about it too much?
