I am experiencing pain, rather sharp, under breast bone. I can t get comfortable. Sometimes intensifies with a deep breath. Can feel it through to my back. I have had this before, about 3 years ago, and it turned out to be a gallstone attack. Though I can t be sure, this feels the same as that. At that time I went to the ER and was thoroughly checked out for heart issues, and then they discovered gallstones with a scan. They apparently dissolved or resolved in a few days. This feels the same, but I worry about it being heart-related. Not sure whether to panic. My EMAIL address: YYYY@YYYY
