I'm amazed, I have to admit. Seldom do I encounter a blog that's equally educative and engaging, and let me tell you, you have hit the nail on the head. The issue is an issue that not enough people are speaking intelligently about. Now i'm very happy that I found this during my hunt for something concerning this.

Went with my husband to the ENT, and showed this to the doctor when he was deciding what antibiotic to give him. He was gonna prescribe amoxicillin, but changed his mind. Thanks for the info.
