you should probably get it checked out to make sure it isn't infected in case you damaged your tympanic membrane.
ear infections, plugged ears, etd etc. can all cause temporary tinnitus. they go away when the infection heals or the ears unplug. I was a victim of both following HBOT treatment. tinnitus due to ETD goes away right after your ear pops open.
also many times if you think your ear is plugged and you can't hear well it could be sudden hearing loss. get your ear checked if there is actually wax in there
