I Have Started Having A Buzzing Sound In My Right

I have started having a buzzing sound in my right ear for about six months. The hearing MD said it was my ear and brain making the noise to let me know that I am loosing some of my hearing, but I am also having a lot of over sensitivity in the middle of my tongue. The foods I use to really enjoy I can not hardly eat now, some because they set my mouth of fire and some because the texture of the food feels like it is tearing my tongue up. Could they be connected and if so by what? Please advice me.
