Annikin, since my PD started on my right side, I had undiagnosed pain that felt like it was right under my ribs. Doctors treated me for IBS and did a lot of colonoscopies and endoscopies. It was only after I was diagnosed that I asked Dr. Okun about it, and he correctly identified it. I did notice that it did not seem to be related to what or when I ate. It hurt more when I was working in the kitchen, so perhaps that had something to do with the misdiagnosis. After the dishes were done, I would sit in the recli er and it would feel better.
