Hi there.
I have a question posted waiting for an answer too, but I just happened to see your initial question and thought I might offer something that I just came upon. I just read that when someone is having heartburn due to gallbladder problems then the area in their shoulder blade could have pain. Have you ever seen this or think maybe this could be the reason for the heartburn? I am contemplating this myself. So many things in one's stomach, it is driving me crazy!
I hope you feel better and find some relief. I hope it was okay to offer this info to you. I am not an expert by any means and am seeking answers myself because something is going on. But I just, and I mean, just read, this info about gallbladder and shoulder blade pain.
Best of luck to you.
Tricia
