My doctors could feel the adhesions. Have they felt your abdomen? Maybe your problems can't be felt. It's not in your head, you are not pretending! kHave you tried to do this on your own? Using my hands and fingers I could feel some of them. Press in where the area is hurting and you might be able to feel a knot like thing. As you press it will hurt more.
Fortunately for me my Internists, PCPs, have been the ones that prescribe pain medication for me. They have felt the adhesions in my abdomen and know I'm in pain. I don't have as many pain/obstruction problems as I did before the surgeries to remove my j-pouch in which the surgeon did a wonderful job of lysing my adhesions. Since it looks like you aren't getting any help from your surgeon and GI have you considered taking pain medication, I use hydrocodone, to help? In my case I had and have not had to increase the dosing. People that abuse these drugs have made it more difficult for people that use them responsibly. Fortunately I never felt more than pain relief from them. I guess if I wanted to get high I could have taken more but I didn't as I don't want to get into an addiction situation. I have cut the dose and the number of times a day I take them since the surgeries where they also lysed my adhesions.
It is affecting your work and quality of life maybe the best option available to you is taking pain medication. I use to wish I could take ibuprofen as it helped my pain before I knew I had UC. I don't know what your thoughts are concerning this but I have taken some, on rare occasions. It's been years since I got that desperate. There are some people that self medicate with things that aren't good in the long run - like alcohol. I don't advocate doing anything like that.
