I, too, might be alarmed with a recommendation for a three month gap between CRT or CHT and what it sounds like is Whipple surgery.

I don't think it is unusual for a shorter gap ... are you certain it was three months and not three weeks?

Is your medical care at a pancreatic center of excellence? If not, please consider quickly being evaluated at one of these ... pancan.org can provide assistance in identifying one. My recommendation is to relocate to one of these centers for all of your treatment - including chemo and surgery.
