Have they done a scan/xray since you had the shunt tubing moved in your abdomen? Mine was wrapped around my diaphragm and then they moved it but it MOVED BACK. So I had another laprascopic procedure in which they just shortened it by a lot so that it can't even reach my diaphragm. I lived with the pain for 9 months though until my pain management dr called my neurosurgeon to tell him, "Listen, she didn't have this pain BEFORE the new shunt was put in, therefore the shunt is almost certainly the cause of the pain" And it was. Be persistent.
