I Have Been Told By Family And Friends (I Have

I have been told by family and friends (I have also noticed myself) that when I talk I sound very congested. It's almost as if there is something blocking my nasal passages. I've known that I've had enlarged tonsils for quite some time, but all the doctors say "that's pretty normal" but I don't seem to think it is. Is it possible for my enlarged tonsils to be causing the blockage? I notice I'm always usually "stuffy" feeling throughout the day, and this is daily. Any advice would be appreciated.
