Suggest Treatment For Sharp Stomach Pain That Radiates To The Back

yes .. I have very sharp pain in my stomach area .. its in one spot on my right side and goes to my back ... then at my belly button.. then one spot in the lower left that goes into my back.. but nowhere else in between .. it hurts worse when i eat.. but always hurts .. today i ate my lunch and literally ten minutes later. i was on my knees screaming and crying in pain... ive been to the emergency room.. first time they thought they didnt not see any blood flow on my right ovary .. i am a female.. and it maybe twisted .. but before i could make an doctors appointment i was back in the er. and they did a ct scan said it was fine,, and said my appenditics was fine... but i have to follow up with obgyn.. could you please help me out .. it feels as if someone has stuck a knife on both side in the same exact spot and goes straight through to my back but its just in those to spots
