Since it's been around a while, if it was a tumor it would have probably eatten your head by now.
Maybe its time to go in for a warranty check! Def
It sounds like an issue with the Hyoid bone, and/or Thyroid cartilage, particularly if you're feeling something going on with your vocal cords.They're probably going to jam it back into place, give you OTC pain killer, and wrap it (REALLY TIGHT) in bandages. As your face turns purple, they'll ease off the pressure... one hopes.In all seriousness, I hope it's nothing major, and that you feel better.
