She is knowledgeable, and two things can be true at the same time. TMJ headaches don’t only show up in one “classic" location. They can occur in the temples, around or behind the eyes, the forehead, scalp, neck, base of the skull, and even the back of the head. A lot of this is referred pain.
Jaw tension can cause pain throughout the head because the jaw, temples, neck, and scalp muscles are all connected. So TMJ can absolutely cause headaches outside the jaw itself.
Tension headaches and blood pressure don’t really “go hand in hand” the way that phrase can sound. What actually tends to go together is stress and adrenaline, muscle tension, and temporary blood pressure bumps. That’s very different from hypertension causing headaches.
Sustained high blood pressure only causes headaches when it’s extremely high, and it would clearly show up in readings. You don’t have that, your numbers are controlled. If your BP were high enough to cause headaches, you’d be fainting, falling over, and ending up in the ER.
So when she linked tension headaches and BP, she was talking about stress physiology, not blood pressure being elevated for weeks. That’s also why propranolol makes sense: it reduces adrenaline, relaxes the physical stress response, helps with tension type headaches, and lowers BP a bit as a bonus. She was smart to prescribe it.
Trusting her expertise doesn’t mean assuming you’ve had dangerous blood pressure for weeks. It just means she explained it broadly. Bottom line: you can trust that she knows her stuff and still know that your headaches aren’t from weeks long high blood pressure.
