Hi Golf,
You can read this TMJ board to find out the answers to several of your questions. I am being treated for TMJ and also had a son who was treated. It is best to go to a dentist who has some expertise in TMJ (just ask), to an oral surgeon, or maxillofacial specialist. The person I am dealing with is a dentist who is in a maxillofacial group, and he specializes in TMJ. I, too, had sinus-type pain and continue to have it after 4 months. My TMJ said that was not a common symptom. It is more of a numb, cold feeling in and behind my nose, into my upper jaw and teeth. I saw an ENT doc to rule out any ENT problems. He examined me twice, did sinus x-rays, all OK. He referred me to a neurologist, who did an MRI of my head. That came out normal. Oh, I also had an MRI of my TMJ joints, as that is the only test that can actually see the soft tissue. Panoramic x-rays are done in the dentist's office, but that only shows the condyles, and not that well, and the teeth. To see the disc, an MRI of the TMJ joints has to be done. Surf this Board to see the myriad of symptoms people experience. Basically, any symtoms in the head could be symptoms of TMJ including but not limited to headaches, clicking, grating sounds when eating, ear problems, locking jaws, etc.
As I said before, my symptoms were mainly a numb-stuffed-up feeling in and behind my nose into my top jaw. I also have a lot of creaking and cracking when trying to chew anything that is not soft. I also cannot open my mouth very wide. My jaws ache, and my tongue is sensitive when brushing my teeth/tongue.
My son's primary symptoms were jaw locking, a feeling that his bite was off, and clicking when eating.
In my opinion, the most important thing is to research to seek out somebody who is truly qualified to diagnose TMJ as it is an expensive condition, and most medical insurances do not cover it. Lots of dentists think they can treat it but are not really qualified to.
Well, I hope this helps.
