I recently return from an Orlando vacation where I visited a different theme park every day of the week and spent most of the day screaming on roller coasters. By the 3rd day, my voice was hoarse and scratchy but i didn't have any pain or soreness in my throat. Thinking it would go away - i continued on, after all I was on vacation. The 4th day I didn't scream on any rides,but from regular talking, I barely had a voice.
Its been 1 week now, and I my voice hasn't returned to normal. Is it possible that I could have done permanent damage to my voice from screaming - How would I know, and what can I do to prevent it from being permanent? I having warm liquids only, and Im making an effort to avoid talking.

Please help!
