Hi TMV, Today I had to upload a few videos for an audition. Basically I sang for a few hours to get the takes just right, and it was more singing than I've been doing lately. Some of it was in the upper parts of my range. Long story short, after finishing everything, I tried hitting my upper notes a few minutes ago and I couldn't do it, I didn't have control over it, and it sounded really raspy, and not in a controlled way. I sound fine while speaking and I can sing lower down, and in the middle of my voice. There is no pain, and aside from the rough sound in the upper notes, there's no hoarseness. Could I have done permanent damage to my voice or is this just from tiredness and improper use of my voice? I admit I don't have perfect technique, and I chose a song that had a few parts that were too high for me. However now I'm worried I have nodules or something. Please do let me know what you think. I'm gonna go to a doctor in maybe 2-3 days if this doesn't change, but for now I'm trying not to panic, because it might not be anything serious.
