Yes, there are. Many AF patients I see have no signs or symptoms of jaw clicking or popping or TMJ. I've found it to be very commonly associated with nervous tension, anxiety and stress more so than with anything else, whether it be candida, AF, whatever. Not all folks with TMJ have AF, but a lot do.
Stress and especially emotional tension commonly creates tension around the mouth, jaw and facial muscles, and is probably one of the most common cause (of all) when it comes to tension headaches. And tension headaches account easily for 80% of all headaches I've seen in the clinic.
