Is phisical blockage usually the wax or it might be something else? Is it possible that there is a high frequency blockage only? My ringing is mostly stronger in left ear. Left ear feels full and sometimes it feels like some kind of pain inside and I still feel my tooth gums kind of swallen around the tooth that had a root canal. Dentist says its ok but i still feel it. Could i be slowly loosing hearing due to something being infected?
