My Right Ear Seems To Be Swollen Or Something .

My right ear seems to be swollen or something . It does hurt not running a fever was sick about three days ago still have a cough but just alot of fluids but my ear when I yawn or burb it seems to pop a little but I can still tell something is going on .... So do I need to go see a doctor or will I go away on its own? And what causes this ?
