I agree with Nelly about getting an accurate diagnosis, but dont agree you need to rush right into surgery. Where in Oregon are you?

Dr. Kai Johanson is in Seattle also a Dr. Kliot whom I havent heard much about.
Dr Freishlag is at UC Davis and one of the leading experts in TOS and one of the authors of the new TOS book. Although I have heard mixed reviews of her , I think it might be worth the trip (fly to Sacramento?) to see her and at least get an accurate diagnosis. She used to be at Johns Hopkins and trained at UCLA with Dr. Gelabart,Jordan etc.

Look at these lists for TOS Dr's http://tos.wustl.edu/What-is-TOS/TOS-Consortium
