<s>[INST]Hello,  I was in a car accident on 4/13/11.  About a week after when I eat it sometimes causes extreme pain in my upper stomach area and shoots thru the ribs either on just one rib or both, then about 30 - 45 mins later it moves to below the belly button above the pelvic bone (sometimes feels like ovary pain) some days it involves gas and lately it has been followed w/ diarrehea that is dark black in color.  Curious if I should be concerned w/ it being after the accident.  The ER did an upper right ultra sound and ct scan of the upper stomach and everything looked good.  Just curious, tysm :)[/INST]Welcome to Chat Doctor .1. The May or may not be related to the accident which happened in 2011.2. It could be a fresh pathology. Similar symptoms are seen in acute gastroenteritis / gallbladder pathologies / renal problems / gastritis.3. To narrow down the diagnosis if you are my patient I would ask for an ultrasound scan - and start treatment accordingly. 4.
