If it’s a common occurrence for you to have a sore throat on the day of the gig, I would pay attention to yourself on a few things. Are you breathing with your mouth open from stress? If so, that will dry out your mouth and cords. Do you have a stomach ache on the day of the gig? You may be activating too much stomach acid and as a result getting reflux. Try and observe your patterns instead of treating the symptoms on the day of the gig.
I teach an online 8 week course and Week 5 is all about anxiety and stress and how the way you think about it can have a negative or positive effect on your voice. There’s a wonderful TED talk by Dr. Kelly McGonigal of Stanford University where she shares findings on the nature of stress before a performance.
