This Started Yesterday Before That I Have Had No Problems

This started yesterday before that I have had no problems before. My ears are like I have been on a plane and are stopped up. I have blown my nose, of course eaten, held nose and blown, took sinus medicine, nothing has helped. I am not sick in any way, not dizzy, no headache, just my ears. It's the craziest thing.
My hearing in a little muffled. Any ideas?
