ears get blocked after sneezing alot after a double ear infection?

so i had a fairly bad double ear infection. i got antibiotics for it of course. im already done with the antibiotics and the pain seems to be mostly gone. but im still having issues with my ears crackling when i yawn or move my jaw. i also feel as if my ears especially my left ear seems to clog after sneezing. my allergies are fairly bad. but i never really had this issue until after the double ear infection. what could be going on? does it just need more time to heal? its only been a week since i finished the antibiotics.
