The circular dark spots superimposed upon your pelvis and rib cage represent normal overlying bowel gas.
Amppan, one way to categorize joint problems is in the cause. Some are from "mechanical" injury, for example from too much running or even from one jarring, destructive movement that tears soft tissue where the bones meet.
The other type are called "inflammatory" and they involve the immune system. They include Rheumatoid Arthritis, which causes joint degeneration. But after 1-2 years of pain, even a plain x-ray would have seen degeneration of the joint if any were present. (So says Dr. MacLean, who is a rheumatologist and also current head of the Internists' group.) However, other types of inflammatory arthritis don't cause bone degeneration. I mention all this because in your About Me you include "arthritis throughout spine" and also various inflammatory related problems (even possibly the GERD in someone who is not overweight). I'd think of seeing a rheumatologist about "spondyloarthritis", if the orthopedist focuses merely on the hip alone. This might even relate to the Brunner's, too.
