What the heck is wrong with my stomach?

I have the same problem, and my dr said it was an episode of Irriatable Bowel Syndrome caused by stress and fatigue. I'm not sure of your lifestyle and what you got going on, but it's a valid possiblity that you just need a break from whatever you're doing. Are you over-worked? under elevated stress at the the moment? not sleeping very well? hopefully things settle down for you soon, and goes away, mine passed just as fast as it came, just give it time. I feel for you until then.
