I noticed I sometimes experience strong pressure in my forehead and eyes that extends to my jaw. It gets to the point where my jaw muscles actually pop when I open my mouth, and although I struggle with anxiety, this symptom happens when i’m not even anxious. Its more the opposite so unfortunately that feeling causes me to panic a little when it occurs because of my hypochondria... 

Is it normal to experience this? I don’t have any sinus or migraine issues so i’m not exactly sure what else to look for if its not the anxiety
