Hi @hopeful33250, in response to your question of whether I have ever had pelvic floor therapy, no I have not. I am somewhat doctor shy...and I do a lot of reading about gastric problems and Hiatal hernia issues. (A definite NO NO from any Doctor!) I found this technique, while searching for relief from a sharp pain on the left side of my chest. (I recently saw a cardiologist, and my heart is not at issue) This technique is for a sliding Hiatal Hernia, which causes thoracic pain and doesn't allow lungs the room to completely fill with air. There are a few slightly different techniques given, but I use the one I posted.
