Hello Dana,
I have been eating light myself to avoid stomach pains and made the mistake of eating a spicy chicken sandwhich. Shortly after that I had severe lower back pains followed by shooting stomach pains. I went to bed and it kept waiking me up all night. I also knew something was wrong when my bladder started hurting as well from the pressure of my intestines. So to answer your question eating certain foods can cause stomach pain.
Thats what I get for eating such a huge sandwich, but dang was I hungry and an idiot. Back to lean cuisines.
