Pain under ribs

I have a pain located in between my breasts but closer to my right side just under my ribs. I though it was my ribs at first but I don't think so. Do you have any ideas of what it could be?

Does the pain go up higher aswell on the right Side and into your shoulder baldes? comes and goes maybe some nausea, I have had this I put it down to the Anti histimines I was taking for Hives I have been battling for a few weeks,I wondered if there was a virus going round, I heard that a Gall Bladder attack was a possibility.
