Left Ear Deafness

I have noticed my two ears usually don't open at the same time when I yawn. I do this a lot to feel my left ear (the one that feels muffled) a chance to feel open and free. I'm not sure if I'm getting hearing loss but I believe that's the most obvious answer. What should I do? Is this curable?!

 

Best to get your hearing checked and ears checked to for wax build up or fluid behind your ear drums....lots of love glynis
