Gp has referred me to a cardiologist to check for floppy valve syndrome, but could the pains in my side be from pancreatic cancer though? at 34 years old, odds are in my favour but dont want to leave anything to chance.

Whoa: Hey Barry, talk about this one with your physician. Physical exam should be sufficient to distinguish musculoskeletal pain -- which we all get in various places -- from deep pain due to some visceral problem. Pancreatic cancer simulating musculoskeletal pain usually is "back pain". The best treatment for worrying about very-unlikely medical disease is to focus on fitness -- hit the gym hard.
