@ryanrayna1 It could very well be an adhesion. It's a type of scar tissue that can attach organ to organ, organ to abdominal wall. My first one was found when my gallbladder was removed. It was sitting on top of the organ which had suffered acute attacks for 7 years before anyone realized what was wrong. That adhesion was removed, then the gallbladder. Six months later, I developed nauseating pain in my upper left abdominal quadrant. Test after test was run. Another adhesion formed (once you get one, you'll be prone to more any time trauma occurs, especially surgery). At times, it feels like a sharp knife, other times, like something is tearing. It can be palated because it's close to the surface. It presses on my stomach (the organ) and my diaphragm. Unfortunately, unless an adhesion is causing more than pain, it will be left alone. This is because, as of now, there is no technique or mechanism to prevent a new adhesion from forming. There is a powder that can be sprinkled which I believe forms a temporary layer meant to prevent an adhesion from forming but, the statistics the last time I looked weren't great. Early on, when I had my surgery, statistics regarding cholesectomy adverse events were very much lacking. Within the recent years, an updated, very detailed list was released.
Unfortunately, the only certain way to diagnose an adhesion is to open the body. That, of course, creates a possiblity of another adhesion occurring. Based on location, it can be felt. But in terms of scans (eg sonograms), not much is particularly useful.
