I was diagnosed stage 1 after successful resection (distal pancreatectomy). My first inkling of any problem was unexpected weight loss way before surgery. Right before surgery in July 2022, I felt some back pain. I went through 12 rounds of Folferinox, but the cancer showed up again on my liver. Throughout chemo, doctor always felt my abdomen to see if I felt pain, but never did. I am guessing that pain would be experienced as the cancer grows. I am now on a Gemzar/Abraxine regimen. Best wishes.
