The TMD pain is in the inner ear, head, jaw, face, neck, and can radiate as low as the chest at times. You may wan to try something like
Zantac (an
H2 blocker) or Prilosec OTC (a Proton Pump Inhibitor) to see whether that helps symptoms. Of course, consult with your doc about this.
FYI, my first symptoms of GERD were about the same as yours. I also had a lump feeling and clicking in my throat which has been virtually eliminated since I started medications about 6 weeks ago.
