I keep getting big rushes of what seems like hunger pains but a lot worse. i also keep getting cramps, is it anything to worry about?

Of course: This is a common complaint in my experience and I have an unusual answer. I predict that your diet is lousy and full of pop, sweets and etc. The pain is due to a signal from the lower brain that is responsible for computing your adaptation to environmental factors. Sugar creates a relative vitramin deficiency that causes the computer to be irritable so its messages to the bowel cause pain.
