Experiencing Numbness And Difficulty In Hearing

I am having an issue with my left ear. For at least the past week, maybe a little longer, I have had very muffled hearing in my left ear. It's extremely bad, to the point I can really not hear much at all on that side. I find myself not even able to hear my husband when he is just a few feet away from me unless he speaks loudly. When I feel inside the ear to try and see if I can feel any wax build up or anything, the inside of the ear feels very numb.. It's a very odd sensation.. I did just get over the flue a couple weeks ago, but the ear issue did not happen until I had been well from that for a couple days.. I have not been around any unusually loud noises or anything like that.. I don't think there is water in there.. I can not hear it or feel it if there is.. I currently do not have insurance so I am trying to figure out if I need to make a trip to the ER or if this is something that will clear itself up.
