The Siberian Husky is not a one-person dog. Nor is he a guard dog. He might let you know someone is around, but he has no concept of protecting you. The Siberian is a friendly and gentle dog who is not overly suspicious of strangers or aggressive toward other dogs.
The short answer is yes, it's entirely possible to have RA in your jaw-RA affects joints and your jaw is a joint. In my personal experience, I find jaw pain one of the most difficult to cope with, it's as if it permeates everything, making it impossible to ignore.
Facial pain can be caused by an uneven bite, meaning that the jaw muscles are not working properly. When these muscles function inefficiently, they experience signs of stress, including pain, swelling and discomfort. Because the jaw muscles run from ear to ear, symptoms of jaw distress may surface in the face.
