Same happend to me with my righ ear i did not mention nethin to my dr, its goin away tho :)
I dont have a hearing loss but my left ear has been ringing for over a month and two days ago both my ears started hurting. When I go to sleep it feels like there is some kind of drainage coming out and they hirt so bad. My obgyn gave me some antibiotics.
Guess I'll bring that up next appt. :(
It doesn't sound like its pregnancy related but I'm sure it would be safe to have your hearing tested during pregnancy or maybe you have an middle ear infection?
