I believe the pain
in your left chest/flank is connected (no pun intended!) to your pelvic pain
...all these areas are connected by muscle tissue and gut lining tissue..If you have extensive scarring like it sounds you may, it all pulls..And this kind of pain
refers to other areas...In the medical field, we call it "tracting"...I'll spare you the technical whys and hows, but just suffice to say, it follows body "channels" from bottom to top...
