I feel like I have air trapped in my lower left eyelid. It s summer break, and I m spending a considerable amount of time on the computer. It often feels like it is twitching, but when Imlook in the mirror, there is no noticeable twitch. I also recently tried contacts, and I spent a lot of time forcing myself to hold my eyes open, though I m not sure if that would have anything to do with it. Should I see a doctor? Or?
