lend me your ears

So I finished that paper at about 2am--better than I was expecting, I suppose. My ears felt a little pressure-like, but I figured that was just exhaustion, so I went to bed. I woke up a while ago & my ears have been pressured all morning--like when you're in an airplane, & you need to pop them? Except they haven't popped. For...many hours! This is driving me crazy. It doesn't hurt, but it is annoying as hell. (I'll go to the health center tomorrow if it doesn't change, but it doesn't feel serious...I just can't get them to pop!)
Does anyone have any ideas? I've chewed gum & yawned until world's end, but nothing really works. Blargh.
