Huge piercing pain in stomach from oranges?

this night I woke up 2am, I was hungry,didin't want to eat anything heavy so I just ate one orange and it was so delicious I couldn't resist ,had to eat 2nd orange,then I went to sleep. In morning I wake up 5am with pain in stomach,it's uncomfortable so I thought maybe I just need to drink water or something to fill my stomach ,when I got out of bed the pain became worse,it was so bad I just sat on floor and grabbed my belly. now I drunk some water,the pain went of for a while,but now I still feel uncomfortable little pain. can it be from oranges? I didin't eat anything else since 6pm , when I was little I used to have alergy for lemons,oranges and anything like that ,but that was long time ago. any advice how to make the pain stop? and pain killers don't work,tried them.
