I ate a hamburger and french fries last night, and during the middle of the night, I had nervous stomach pain, (it almost felt like something was moving around inside of me, or colon acting up, motility. Also, my heart rate was up, beating faster, then went back to normal. I woke up this morning, doubled over with I think might be gas pains, very painful, bloated, as I am sitting here typing. What is this ??
