Well guys, I am 1 day out of my revision surgery. My doctor found that the tubing from my port was rubbing against my diaphragm and that was causing my shoulder pain. My dr told me that when he was a generalist, when a person had a car wreck, and they were hit in the side, to determine if they had a spleen injury, because the spleen is directly associated with the diaphragm, they would ask if you had left shoulder pain. So, maybe you guys can get relief. I show hope I do. Good luck!
