I have developed a large lump in my throat right behind my tongue, but where my right tonsil is. This lump is about the size of a ping-pong ball and makes it very hard for me to swallow and breath and makes my voice sound funny. I have a doctor's appointment but they couldn't see me for a month. Any ideas what it my be? It doesn't hurt, it's hard, it's red and it is only uncomfortable because of the breathing thing. Any help would be appreciated. Thank you!
