Tension in tonsil area. Yes I still have mine.
The sensation of tonsils swelling is what I experience when attempting certain songs that have extended passages of higher range songs that offer little opportunity for taking breaths. One song, Maroon 5's "One More Night", seems impossible to me to complete from beginning to end. Invariabily I get the sensation of my tonsils swelling until my throat is basically shut. This happens no matter how much attention I devote to staying relaxed and maintaining proper breath support.
Does the presence of tonsils present an additional challenge to singers? Really I'm not looking for excuses, and I've never heard anyone discuss the presence, or lack thereof, of tonsils as a factor in singing ability, but this is where I experience my greatest challenge - swelling in the tonsil area.
