The ultrasound is not the best test to visualize the pancreas. A CT is the better study. If there is continuing concern about the pancreas, an MRI can be done and will be the most detailed study.
If these tests continue to be normal, then it's unlikely that pancreatic cancer is present. You may want to look at other causes for the symptoms - whether further GI tests (i.e. upper endoscopy) or look for a musculoskeletal cause (i.e. MRI of the spine looking for any disk disease).
I am not aware of excessive gas being a symptom of pancreatic cancer - although that doesn't mean it isn't possible.
Followup with your personal physician is essential.

I personally would recommend lab work done like CRP levels, Amylase, CBC etc.
Upper GI endoscopy should be performed again even if negative initially because false negative results can always come out.
Some docs dislike alternative approach, rather look down on it. Here is a personal example:
I know an RN who once worked with me in ICU. Presently she has weakness of her extremities & no doc has been able to diagnose her condition with confidence. In the end when some of us in Neuro can’t find a diagnosis we have a tendency to label the patient with MS.
She got so disappointed & turned to alternative med, weekly IV Glutathione therapy along with physical training & is getting better. That’s what all counts.
