Doctor Gary to the rescue! OK, this one is the easiest of all problems to solve. When I was a much younger man, and working 6 days a week in the broadcasting biz doing local and national news, there were times when your through was just shot to hell. I did 15 minutes of news at the top of each hour, and another 5 minutes at the bottom of the hour. That's hard on the vocal folds.
I came in one morning to begin broadcasting the news and I was down to a squeak after the first 15 minute shot. The news director said "Go to the refrigerator, take out either the jar of sour onions or dill pickles, whichever you like the best, eat one before the broadcast and you'll be just fine." HE WAS RIGHT!
I didn't understand this until years later when I worked with a top ENT surgeon who said
the vinegar and spices used to make pickles anesthestizes the vocal folds and the effect last up to 30 minutes in most instances. However, he also said when you loose your voice from overuse, this was just a short term remedy--not a cure. The cure is to gargle with warm, salt water (1 tsp. per 8 ounce glass) 4 times a day and allow your voice to rest for a few days. I've had one polyp removed from my vocal folds, and it scared the hell out of me.
I don't have to work hard to sing, I don't have to strain my voice to belt out a song, but I have a relatively deep voice, therefore not as subject to sore throat problems from overuse. But, when it does get sore, and the soreness lasts for more than a day or two, I head for the ENT doc--just to be safe. A lot of famous singers died from throat cancer--I don't want to be one of them.
Don, Make that check payable to: Doctor Gary!
