What are some possibilities of left side abdomen pain?

Hello health conscious jellies!

So around 10pm last night while sitting on my chair I felt a little pain in my left side. It’s like a very mini constant cramp. It doesn’t bug me, but I do notice it there. I still have the pain this morning and usually when I sit down and play video games on my computer for about 3 hours straight I get a sharp pain in my right side. Well I don’t have that pain yet the left one is lingering.

It is below the rib and 6 inches to the left of the belly button (I’m a small fat guy)

I changed my diet starting Monday gone straight veggies. Yesterday I had a Blonde blende Starbucks tall coffee, banana bread, bean and cheese burrito, queso jalapeño chips, and a large hot tea from The Living Room cafe. I honestly don’t remember drinking a whole bunch of water yesterday, but I know at least 1000mL of water so about 2 Arrowhead water bottles.
