I am experiencing pain in my upper left side, around the rib area. The location of the pain keeps changing from under the front lower ribs to pain in my side (about 5 inches below armpit, but still on ribs), but it pretty much constant and has been going on for days now. I've committed the cardinal sin and googled and I keep thinking it's either something to do with my spleen or pancreatic cancer . It's really doing my head in. I've had a bit in the past (a few months ago) but it seems more intense now and I can't stop thinking about it. Anyone think of any benign reasons for this? I don't think it can be IBS because I don't have any bowel or digestive symtoms.

Thanks guys
