So all this pain was from simple constipation, which was caused by improper diet. Applemint is probably young... as she reports that she's immersed in important school examinations... and she probably eats a lot of high-energy "junk" food... typical habit of harried young people. This is a prescription for constipation.
Applemint mentioned she was eating bananas, probably in reaction to advice to eat fruits and veggies. I did that, and drank apple juice, for the same reason. This did not help my constipation, years ago. Then when I married and became a father, my wife brought up the subject of the "BRAT" diet, to abate runny stools in kids. That acronym stands for BANANA, RICE, APPLES, and TOAST. These items, therefore, counteract and do not support one's wish to abate constipation.
So not all fruits are created equal, in this regard.
Once again, I am encouraging young people, in particular, to wise up on this subject which warrants conversation among old people, but, unfortunately, not young people.
In a word, constipation is DIETARY, and there must be plenty of it going undiscussed, thanks to all the junk food that young people eat.
