tinnitus ?

okay so just a few days ago i went to sleep with my earphones in my ear and unlike most days when they fall off my ear when i’m sleeping, i woke up with it still in my ear. when i woke up my ear felt weird after sleeping with that sole ear pod in and i got a bit of tinnitus. it’s by no means horrible but sooo annoying and i have no idea what to do or what caused it. however, the inside of my ear sort of feels stuffed? could it be wax? ear infection? also, it only seems to be on that one side. i’ve had tinnitus that lasted a few hours before caused by listening to very loud music. please help!!
