Is it common to have a sore throat after starting the program? I just started the program this morning. 

Hi Ray, pain is not a sign you should ignore - that's your body telling you to stop, rest, and try again when you're feeling good. Please see below for advice from another thread on strain/pain!

I'd start by adding in a cooldown to the end of your practice. Here's a 4-minute cooldown for low voices. Your cooldown can also be as simple as a minute or two of gentle slides/sirens through a straw. 

I'd encourage you to send in a video for feedback as well, particularly if there's something you can pinpoint that causes you strain/pain in the moment: https://www.30daysinger.com/feedback. 

If you're concerned and the hoarseness persists, it's worth checking with your doctor to address any underlying issues that could be contributing! Our rule of thumb is: hoarseness for 2+ weeks warrants seeing the doctor.
