i have has mucus in my throat for about a good month. I had some kinestheology muscle testing done, and not only did a chiropractor fix my hiatial hernia i didnt know i had, but she told me i had some leaky gut to heal.
she then informed me that with leaky gut, your body gets minor food allergies that it never had before leaky gut, since things are leaking out of where they are supposed to, and its common for mucus to line the digestive tract as the systems trying to protect itself. which, of course, includes the throat
