Last night I vomited and about 10 minutes later I had a sharp pain in my chest that went in to my upper abdomen. The pain seemed to go away but when I would lean over I would feel it. The pain went away last night and I was okay even until this morning. At random points through out the day the sharp pain comes on and off on my left side of chest right near my rib cage and also on and off the same pain in between my belly button and sternum. I do suffer from chronic heartburn and indigestion. Any idea what this could be? Also, hiccups will shoot the pain in my chest
