What is this sharp pain I feel in my stomach?

For the past 3 days I have had sharp pains going through my stomach. They are on and off, sometimes they last a few minutes sometimes hours. I have no clue where they are coming from. It all started 3 daya ago. I used the bathroom and when I got finished I began feeling these sharp pains in my stomach. Felt like they were coming from my the bottom of my private area to the top of my stomach. Every time I moved the pain got sharper. Yesterday I got off work and ordered some chinese food. I had a small plate, but I only ate half of what I ordered. Soon as I finished the pains came back. Today I came home from school took a shower and made me some vegetable soup with no meat because I was afraid that was the reason my stomach had been hurting so bad. While my soup was simmering I took a nap. I set my alarm for 1 hour 15 minutes before my alarm went off for me to get up the sharp pains woke me up out of my sleep. About 2 hours went by and then tthey just stopped completely. I ate a little bit of soup and felt fine. What is going on? What could be the cause of these pains? Is it what Im eating? Someone said it was gas and bloating. I do have really bad attacks of gas on my stomach but never so severe.I can usually drink ginger ale or take a gas x and it disappears. Never so sharp and painful just going through my stomach throbbing. I don't know where these pains are coming from so feel free to offer any serious advice. Thanks!
