Hi, all! I'm a newbie to this board and this old thread came up in my Google search and again, I was shocked.
I have TMJ, but I too also have Gastroparesis, which is an autonomic disfunction of the Vagus Nerve, which causes the stomach not to digest food properly. It goes hand in hand with my many autoimmune diseases, Rheumatoid Arthritis probably being the worst of that bunch. I also have other issues with the vagus nerve that cause dizziness, vertigo and near fainting spells and nausea with the right triggers.
The reason I'm posting on this old thread is that I was just shocked to hear of a connection to my TMJ and the motility issues. I shouldn't be, as every year I discover how connected all of my health issues really are (my Rheumatologist was not surprised at all to hear of my recent dx with Gastroparesis, as she said that and autonomic issues are very common with autoimmune disease).
The reason I was Googling today was because in the past year and a half I have been having tension/migraine headaches that won't quit. Today, I am on day 4 of one - ugh! I think grinding my teeth at night triggers tension in my neck, shoulders and jaw, which then triggers the migraine, which causes pain and nausea that take me out for days at a time (not easy with young kiddos)! I had never heard of the correlation with the Vagus nerve in all of this, so I am thankful for this thread and will be taking the info on to my Rheumatologist and then on to the Neurologist that I have been meaning to see for the last year! I just wish there was a doc who could put together a comprehensive treatment plan, since I have so many issues and many are probably intertwined. Specialists are great, but they are just that - so specialized that they can't treat you as a whole person and General physicians are just that - so general that they can't know enough about every system of the body to put it all together. So, I have a football team of doctors and I'm the only one to know the whole picture because they don't have the time (or the insurance company won't let them have time) to sit down and get the big picture
Anyway, sorry to go on and on. I just thought it was an interesting connection that the original poster made and I'm thankful!
