Thanks for the reply. From what I've been told this is part of the process at OHSU when they evaluate achalasia patients. I believe they are trying to find out if anything more than achalasia is effecting your swallowing. There's work in the swallowing and voice clinic which is part of the hospital.
I've talked to them in the past and I don't know whether or not they can actually help the swallowing problems that are caused by achalasia. The area of the esophagus is the bottom. The one I talked to could have also not known much about the disease. It is rare. So I guess I'll have to wait and see.
