I am due to leave for Disney in 8 days!

Last Saturday my left ear started echoing, on Monday morning I went to the doctors and saw the PA. She said my ears looked clear, no fluid or redness but perhaps I had some sinus congestion. I've been taking sudafed all week long. The echo is still there. I don't feel like I have a cold but I do feel a little stuffy.

Last night I woke up with very mild ear pain, but I was able to go back to sleep without a problem.

Is it possible I have an ear infection behind my ear drum?

I am planning on calling the doctor first thing Monday morning, but I am wondering if I should perhaps go to Urgent Care on Sunday...

I've been trying so hard to stay healthy!!
