Several years ago, you responded to a post about severe epigastric pain. Therein, you made a connection to the menstrual cycle/hormones. I am currently being evaluated for gallbladder disease. I already know I have stones but I'm not convinced my pain is entirely gallbladder related. It starts as a really bad burning sensation right behind my sternum that spreads across my stomach into excruciating indigestion. Here's the kicker: I am most likely to get this pain right before and during my periods. I've mentioned this to my doctor who has brushed it off as unrelated. I am terrified that I will get my gallbladder removed only to be faced with the same pain every single month. Do you have any actual research you can point me to that I can bring to my doctors to enlighten them? Thanks!
