I have a follow-up appointment with my doctor in a few weeks. She doesn't know much about celiac, so every time I see her I bring a few little factoids that I've picked up (mainly from this site) and some articles from Medline. At first I thought she would be offended by this, but she actually appreciates it. The fact that she's willing to learn and listen to me makes her a better doc than any of the previous ones.
Before cutting out gluten I had intense sinus pain and TMJ. She sent me for CAT scans, which can back negative. I also had my wisdom teeth removed in case that would help, and it didn't. She's a bit dubious about the sinus pain/TMJ link to celiac, but aside from explaining to her that other people have the same symptoms, I'm not sure exactly why.
Does anyone know the technical reason why celiac causes these kinds of facial pain?
