What Causes Sharp Pain In The Stomach At Night?

Hello, For the last several months. I have been experiencing a very sharp pain in my stomach and back during the night. It often wakes me up as it can be quite severe. Usually, after a while of moving around and showering, it slowly goes away on its own and I m fine the rest of the day, except for feeling a little beaten up. I am hating the idea of going to bed every night since no doubt, it will wake me up. I thought it was my bed but I ve slept in other rooms and have seen that it is not that. I recently (6 wks ago) had a hiatal hernia repair re-do and thought it could be that, but I don t believe so. I am very worried about this and am concerned that it doesn t go away.
