Hi there....I have been in neuromuscular tmj treatment for about a year now...and in the beginning...I had horrible swallowing issues, esophageal spasms that were so bad I couldn't eat sometimes, and major muscular pain in and around the hyoid bone....From what my doctor has told me, when your mandible is positioned too far back...it will create swallowing issues, because of the lack of room for proper tongue function...and create muscular issues. Also, there is an 80% overlap in TMD cases...and sleep apnea...so that is nothing to be ignored either. In my case, I am wearing a neuromuscular lower orthodic 24/7, to reposition my jaw into a more down and forward position, eliminating the grating noises in my joints, and a great portion of the muscular dysfunction. Over time, the muscles will adapt to this proper position, and then phase 2 is usually addressing how to correct the bite to match the new jaw position. I will need expansion, because my upper and lower jaws are too narrow...and possibly functional jaw ortho. to move my teeth that have shifted. I am also addressing postural issues with A/O chiropractic, physical therapy, and craniosacral therapy to address cranial misalignments. I hope this helps.
