(Concern) I experience stomach cramps once in a while.

I am in my late 30s, and my eating habits tend to be salty, sweet, and spicy! I eat a lot, so I suffer from gastritis and esophagitis... I have had a few endoscopies, but I experience stomach cramps once every couple of months. Actually, I didn't even realize they were stomach cramps... The pain in my upper stomach suddenly feels like my throat is suffocating, and later I think it felt like squeezing... Is it a stomach cramp... or could there be a problem with my pancreas... I'm a bit scared to go to the hospital, but I'm worried...
