I've recently been having bouts of significant pain/discomfort in stomach, direct center not the usual right sided discomfort I get. This comes on fairly suddenly and makes me nauseous to the point of vomiting. At first I thought it was due to fatty foods but it just happened and I haven't had anything to eat that should cause this. Does anyone else get this and have you found it's related to gallbladder, PBC or maybe something else? Has happened 2 or 3 times in the last month. Thanks for any words of wisdom you might have!
