Episodes of pain in upper abdomen

I've been wondering if there's a possibility that I may have some sort of pancreatic disorder, as I've experienced several episodes of severe pain in my upper abdomen that radiates through to my back.The pain gets really intense - I have difficulty breathing, become nauseous, and start to sweat.Although, except for the one time that the pain lasted 1-2 hours, whenever this occurs, it only lasts about 20 minutes. I've also been feeling like I am experiencing a lot more heartburn than usual. In case it's relevant, I don't smoke and I don't drink much (1-2 glasses of wine every couple of months or so), but I do think that drinking any alcohol causes the heartburn to increase.I'm just afraid the problem may be getting worse, since I've experienced this pain twice in the last few days. This is very uncommon for me.Is this something I should have checked out, or could it simply be a common experience?

Thanks for any advice you may have to offer.
