Hi. For The Past Couple Months My Right Eyelid Closes

Hi. For the past couple months my right eyelid closes for about 5-10 seconds after I sneeze or when I yawn--every time. It's almost like a twitch, but it doesn't twitch, it just closes most of the way. I have to forcefully open my eyelid again by trying to open my eyes as wide as I can. But it's not easy to get it open. It's like I'm fighting against the eyelid muscle or something. I'm sure it's nothing, but maybe you can enlighten me on it. I don't want to waste a copay on a doctor's visit and have her tell me it's absolutely normal.
