Should I be concerned that my ear has been plugged up for 3-4 days?

I’m not prone to ear infections and have only had a couple in my life. I had a cold for a week, started to get better, then got hit hard by another cold. The first cold, I happened to have a doctor’s appointment and she checked my ears and they were fine.

The second cold has been more unpleasant. I’ve had a sore throat every day since it came on (five days ago); the sore throat is now pretty mild, but still there. My lymph nodes on my neck are sore. Both my ears were plugged up, my left one is now fine, but my right one won’t pop. I started having some mild pain in my ear, but I wasn’t sure if it meant it was getting ready to pop or what.

I just want to know if it’s within the range of normal to have an ear plugged for so long, or should I go scurry to Student Health?
