Sometime several months ago, while singing along with a song in my car, I (like an idiot) resorted to screaming/belting my lungs out to force myself to reach a note that I cannot reach without strain. Since then, my voice has become a gradual problem for me - I'm a theatrical performer and typically perform in two to five shows per year.
The area around my Adam's apple feels much more restricted, as if someone was very lightly pushing on it every second of every day. Whenever I swallow I can feel it push out momentarily before receding back in. My speaking voice has a rough vibration to it whenever I speak slightly lower than regular, and my falsetto range is almost entirely gone; notes that I could hit without effort are now becoming a task. It's not simply a situation of my voice changing either - at times I will begin to sing high and my voice will break in and out. I'm completely unsure of what to do, as I'm praying I haven't done permanent damage to my vocal chords.
