I am having an almost grinding type of feeling that filters what feels like all through my stomach , right underneath my right pectoral, and in most spots of the stomach from the chest down. My bowel movements have rarely been brown, for a period they were dark, potentially tarry stools , that passed, but very few have been solid and brown, the most recent mixed with green and brown. Slight stomach pains that aren t extreme pain, but this is all consistent leading me to believe it may be something.
