is this GERD related?

hi ya'll!  i've finally started calming down with my anxiety problem of not being able to breath and now its just when i eat the foods im not allowed to cuz of my GERD. so thats a good thing!  but at the same time im starting to get the more tightness in my throat and my jaw area is always tight and my nose is always stuffed. is this gerd related?  also, from GERD do you guys ever experience a heavy chest?
It sounds like more of TMJ problem, but gerd has been known to be linked to TMJ. I have TMJ and have a splint made by my dentist I wear that has helped heal it almost 95%..do you clentch or grind your teeth alot? This will also cause sinus problems.
I have felt the heavy chest with GERD, and chest pains..alot of people mistake it for a heart attack and vice versa..
