On May 11, 2010, Glee aired its eighteenth episode titled "Laryngitis". In this episode, Rachel suffered from a lost voice which was attributed to tonsillitis or is it laryngitis . It was a bit confusing as it would seem her lost voice was attributable to laryngitis (title of the episode), but than she was diagnosed with tonsillitis by the TV doctor which really has nothing to do with laryngitis. I guess it is possible that she had TWO conditions going on at the same time even tho…
