Weird Back Pain and Tailbone Pain

Wondering if anyone has experienced pain in their back and tailbone after losing......I have lost a total of 50 lbs and now when I sit for extended periods of time. My tailbone and middle of my back hurt.

I also have port pain from time to time. Will this always be the case with the port? Sometimes it shifts and moves. OuCH

Not sure about the back pain, but maybe you have lost some of your "cushin."  I guess the pain could radiate up the back if you are in pain.

I have also been feeling the port.  Mine is not so much pain, but an uncomfortableness.  I find if I lean to the side or adjust the way I am sitting it gets better.
