“Mast cells tend to hang out at the body’s environmental interfaces (to best serve their defensive role).”
That’s a short but very important quote from the book, Never Bet Against Occam: Mast Cell Activation Disease and Chronic Illness.
Do you have dry, itchy, gritty eyes? Ever have a dry cough, where it feels like no matter how much or how hard you cough, you can’t get rid of the itchy feeling in your throat? Or how about itchy skin? All of these are your body’s “environmental interfaces,” where mast cells are trying to protect your body. (These are also symptoms of mast cell activation disease.)
