I had the same symptoms and problems as everyone on this post. I had three surgeries and seven organs removed. The adhesions and scar tissue covered the pelvic saddle and connected up to my 2nd ribs and to my spine just above L4. Over time the adhesions became harder, obstructions increased and spine and hip movement was restricted. My surgeon and Gi gave up and told me I had to learn to "just live with it."
Luckily my Gyn stepped in and referred me to a physical therapist specializing in scar/adhesion treatments. It is a combination of exterior and interior massages and exercises to stimulate the areas that almost atrophied from lack of movement.
The first three weeks were very painful. After four months the scars and adhesions are nice and soft. No lumps by the stoma incision. My back is the only place still receiving treatment. The adhesion to my spine is still pretty hard but the pain is gone!
