Sudden and intense stomach pain

It comes on every few minutes so it is on a cycle or its some type or spasm . I am pretty sure it is my stomach. The pain starts on either side of my lower ribcage and meets on the middle just below my breast plate and gets very intense and then subsides and starts over. This travels across my torso, not up and I do not have any acid coming up or heartburn.  I seem to have a lot of gas, but passing gas does not seem to help. I have also been burping a lot.  

The pain doubles me over and seems to stay strong no matter my position. It wakes me up in the morning and does not get better with food and cool water makes it hurt worse.

Does this sound like an ulcer?

I started omeprazole today in case it is an ulcer. I am going to be having a scope done.
