This may sound strange; but my mother did this for me when I was a kid. Get Dr. Pepper and heat it up. After it is hot squirt some lemon juice in it. It tastes good and feels great on my throat. Any other suggestions?
Gargle with salt water or use some throat spray.
I just heard the other too that if you rub Icy Hot on your neck, it will help. I haven't tried that yet but I heard it does work. If you try it, let me know.
